An investigation was taken up to study the nutritional value, extent of genetic variability and genetic diversity in advance breeding lines and chickpea varieties grown in Andhra Pradesh, India. Protein and micronutrient content (iron, zinc, copper and manganese) varied significantly among 54 genotypes. Protein content ranged from 9.5% to 24.9% while micro nutrients varied from 2.6 mg/100 g to 14.6 mg/100 g for iron, 3.5 mg/100 g to 7.7 mg/100 g for zinc, 0.5 mg/100 g to 3.2 mg/100 g for copper and 1.6 mg/100 g to 3.4 mg/100 g for manganese. Moderate to high genotypic variability for protein and micro nutrient content with high heritability and genetic advance indicated the scope for enhancement of traits through selection. Genetic diversity studies revealed five different clusters and that high protein lines are grouped in cluster I and lines with higher concentration of micro nutrients are grouped in clusters IV and V. Systematic hybridization between promising lines for protein and micronutrients chosen from these clusters is suggested to study their combining ability and subsequent use in breeding programmes intended to breed for superior chickpea cultivars.

High Heritability

Vegetable soybean production is dependent on the development of vegetable type varieties that would be achieved by the use of germplasm to evolve new agronomically superior yielding vegetable type with beneficial biochemical traits. This can be accomplished by a better understanding of genetics, which is why the research was conducted to reveal the quantitative genetics of vegetable soybean genotypes. Genetic variability of main morphological traits in vegetable soybean genotypes and their divergence was estimated, as a result of the magnitude of genotypic variation (GV), and phenotypic variation (PV) of traits varied among the genotypes. All traits showed high heritability (h2) associated with high genetic advance percentage mean (GAM). Therefore, these variable traits are potential for genetic improvement of vegetable type soybean. Genetic diversity is the prime need for breeding, and the magnitude of genetic diversity values were maximized among specific genotypes. Eight clusters were found for all genotypes; cluster VIII and cluster I were considered to have the most diversity. Cluster VIII consisted of two genotypes (GM-6 and GM-27), based on the mean outcomes of the high yield attributing traits. Hence, these two (GM-6, GM-27) genotypes can be advanced for commercial cultivation; furthermore, other genotypes can be used as source of breeding lines for genetic improvement of vegetable soybean.

The Sorghum genus is extremely diverse both morphologically and geographically, however, relatively few of the 25 recognized species have been evaluated genetically. The apparent lack of basic knowledge pertaining to the levels of genetic diversity both within and between the 17 Australian wild species is a major obstacle to both their effective conservation and potential use in breeding programmes. Twelve Sorghum bicolor-derived simple sequence repeat (SSR) markers were evaluated for cross-species amplification in all 25 Sorghum species. The SSR markers were highly polymorphic, with diversity indices ranging from 0.59 to 0.99 with mean of 0.91. Five markers combined were able to differentiate 24 of the 25 Sorghum species, with intra-species polymorphism apparent. Sorghum bicolor-derived SSRs have proven to be an efficient source of markers for genetic diversity studies of the relatively poorly characterized Australian indigenous Sorghum species.

Nei's Genetic Distance

Knowledge on genetic diversity is necessary to determine the relationships among the genotypes, which allow the selection of individual accessions for crop breeding programmes. The present study aimed at assessing the extent and pattern of genetic diversity within a set of 251 sorghum genotypes using SSR markers. A total of 393 alleles were detected from the 251 genotypes, with the number of alleles ranging from 2 (Xcup11) to 24 (Sb5-206) and an average of 10.07 alleles per primer pair. Pairwise Wright's FST statistic and Nei's genetic distance estimates revealed that the race and geographical origin were responsible for the pattern of diversity and structure in the genetic materials. In addition, the analysis also revealed high genetic differentiation between the rainy and post-rainy sorghum groups. Narrow diversity was observed among the different working groups in the rainy (restorers and varieties) and post-rainy (varieties and advanced breeding lines) sorghum groups. Neighbour-joining and STRUCTURE analysis also classified 44 elite lines broadly into two distinct groups (rainy and post-rainy). However, limited diversity within the rainy and post-rainy sorghum groups warranted an urgent need for the utilization of diverse germplasm accessions for broadening the genetic base of the Indian breeding programme. The diverse germplasm accessions identified from the mini-core accessions for utilization in breeding programmes are discussed.

An intraspecific hybrid breeding program involving six crosses, Palam Sumool (PS) × Palam Priya, PS × Pb-89, PS × Azad P-1, PS × Palam Triloki and VRPMR10 × Sugar Giant, Green Pearl × DPP-9411 was initiated in 2006 onwards followed by pedigree selection, resulted in isolation of 45 genotypes with desirable attributes. These progenies along with five recommended varieties were evaluated during 2014-15 to assess degree of divergence. A considerable genetic diversity was observed among genotypes, dispersed in 18 diverse clusters. Of these, 17 were monogenotypic while cluster I had maximum genotypes. Internodal length contributed maximum towards total genetic divergence followed by nodes per plant, protein content and average pod weight. Superior performing genotypes viz., ‘DPP-2011-SP-7’, ‘DPP-2011-SP-17’, and ‘DPP-2011-SP-24’ from cluster I and ‘DPP-2011-SP-6’, ‘DPP-2011-SP-22’ ‘DPPMR-09-1’, ‘DPPMR-09-2’, ‘DPP-2011-SN-5’ and ‘Palam Triloki’ from monogenotypic clusters offer promise for their direct use as varieties and as potential parents in future breeding programmes.

The potential of a crop to favorably respond to breeding programs depends on its existing nature and magnitude of genetic variability, heritability and genetic advance. An experiment was conducted with eighteen Brassica genotypes following Randomized complete block design (RCBD) with three replications at the field of the department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh, Bangladesh to estimate genetic divergence, variability ranges and contribution of each trait towards genetic diversity. Analysis of variance showed significant variation among the genotypes for all the studied yield and yield contributing characters. The phenotypic co-efficient of variation (PCV) was higher than the genotypic co-efficient of variation (GCV) for all the characters measured, indicated that the traits were influenced by environment. All traits showed high heritability (61.54% to 98.64%) which indicated possible improvement through selection. High heritability values (>60%) along with high genetic advance and genetic advance in percentage of mean indicated prevalence of additive gene action, which provides good scope for further improvement by selection. The genotypes were grouped into four clusters, most of the genotypes were grouped into Custer I (8 genotypes), while cluster IV contained only one genotype. Considering the mean value, the cluster IV and Cluster II were ranked as the top groups in terms of yield and early maturity. High Heritability with high genetic advance in percentage of mean was observed for number of branches/plant, number of pod/plant, number of seeds/pod and yield/plant and selection focused   on these traits could be useful for future breeding program of Brassica. The genotype BD-7114 was the best performer considering all the studied traits especially yield and days to maturity which could be used as an important breeding material for the improvement of Brassica.

Selection Stage

Corn (Zea mays) is a cereal crop and has become a staple food. Purple corn has more excess compared to corn in general. In addition, purple corn has high nutrient content and anthocyanin levels. This study aims to determine genetic parameters such as variability, heritability, and genetic advance of the F2 generation resulting from an open-pollinated hybridization. The research was conducted from January 2020 to June 2020 on the Research and Experimental Field of the Department of Agrotechnology, Universitas Bangka Belitung. The work used a single plant design. The lines used were derived from the results of the previous selection stage. The results showed that the phenotype variability was relatively wide on the weight character of ear cobs with cornhusk, and the cob weight without cornhusk. High heritability values are found in the characters of harvest age, age of male flowering, and age of female flowering. The value of expected genetic advance for high expectations is found in the characters of plant height, the row number of seeds, the weight of 100-seeds, and the weight of cob with cornhusk. The selection results suggest nine corn lines that can be used for the next generation selection.   Keywords: corn, expected genetic advance, heritability, purple, variability

Understanding of genetic diversity among the genotypes is the mainstay of plant breeding. The present study was carried out to determine genetic divergence among 59 common beans genotypes collected from North West Himalaya for nine agromorphological traits. The analysis of variance depicted significant variability among genotypes for all the traits under study indicating wide range of variability present in bean genotypes. The phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was high for seed yield per plant followed by days to bud initiation. High heritability was also observed for all traits except pod length. Cluster analysis grouped bean genotypes into five distinct clusters. The genotypes under group II, III, V have more number of pods per plant, seeds per pod and single plant yield which can be utilized as potential donors for enhancing the yield of other genotypes in breeding programmes. Hence, the selection based on these yield contributing traits may helpful in future crop improvement programmes

Knowledge of the magnitude of genetic variability, heritability and genetic advance in the selection of desirable characters could assist the plant breeders in ascertaining criteria to be used in the breeding programmes. Twenty three introgressed oil palm progenies were evaluated at the Specialized Centre for Oil Palm Research of Cameroon, from 2004 to 2014 to estimate performance, genetic variability, heritability and genetic advance of oil yield and some economic traits in terms to select new oil palm parent materials with the traits of interest. The results revealed high variability among oil palm population for all the characters. Moderate estimates of the phenotypic and genotypic coefficient of variations associated with high heritability and moderate genetic advance as percent of mean were obtained for characters of fresh fruit bunch, bunch number, oil yield, kernel to bunch, kernel to fruit, kernel yield and height increment. The results suggest the effectiveness of selection method for these traits and their improvement through their phenotypic performance. LM11087T x LM2749D and LM12960T x LM7409D were obtained as superior oil palm crossing parents with the potential production of 6.26 ton ha-1yr-1 of crude palm oil; they can be exploited in seed production and further breeding program.<br /><br />Keywords: genetic advance, heritability, introgressed progenies, oil yield, Phenotypic<br /><br />

The present study was conducted to compare the genetic variability parameters among selfed lines of population A (PDM 53 x PDM 4441) and population B (HKI 1105 x HKI 323) and also random mated population A (PDM 53 x PDM 4441) and random mated population B (HKI 1105 x HKI 323) using original inbred parents and three commercial checks, HM-4 (National check), CPB 468 and TENDER (Private check). High heritability coupled with high genetic advance was observed for number of cobs per plant, husked cob weight, dehusked cob weight, baby corn yield with and without husk per plant among selfed populations and a similar trend was observed in random mated populations except for ear length and days to 50 % silking. In total the variability observed was more in random mated populations than selfed lines because allelic frequency differences occur in random mated populations and the pool of gametes originating from male and female is different when compared to the pollen source in selfed populations. The frequency of transgressive segregants were more in random mated Population A (PDM 53 x PDM 4441) and the most promising transgressive segregant identified can be used in the further breeding programmes.
