Mode of inheritance and association of seeds per head, yield per head, blotch and flower color were studied in two crosses of safflower (Carthamus tinctorius L.). Data were taken on individual plants. Mather and Jinks’ three-parameter model indicated that gene action for seeds per head and yield per head showed additive and dominance gene action. The broad-sense heritability for seeds per head and yield per head ranged from 50.75 to 56.02%, and 50 to 57.14%, respectively. Maternal effects were absent for seeds per head and yield per head. In all F2, continuous distributions were observed, suggesting multiple factor inheritance for seeds per head and yield per head. Two loci may be involved in the inheritance of blotch (a new trait) and flower color. Flower color and blotch were inherited independently. Also, flower color and striped hull were inherited independently. A 18 ± 5.6 map distance was found between anthocyanin pigmentation and blotch. Seeds per head and yield per head were not associated with anthocyanin pigmentation, striped hull, flower color and blotch. A significant-positive correlation coefficient ranging from 0.86 to 0.88 was found between seeds per head and yield per head.

The parents, F1 and F2, from four crosses of safflower (Carthamus tinctorius L. and C. palaestinus Eig.) were studied to estimate heritability, gene action and mode of inheritance of head number, seed weight and seed yield. Low variances of nonsegregating populations suggested that environmental effects on seed weight were not strong and that variability was largely genetic; however, environmental effects were strong on head number and seed yield. Maternal effects were nonsignificant for all traits studied. The broad sense heritability estimates ranged from 4.4 to 16.7%, 21.7 to 81.8% and 66 to 85.5% for head number, seed yield and seed weight, respectively. In all F2's, a continuous distribution was observed, suggesting multiple factor inheritance for head number, seed weight and seed yield. Mathers and Jinks' three parameter model indicated that epistasis was not important for head number and seed yield; however, epistasis was important for seed weight. Flower color and anthocyanin pigmentation of cotyledonary midvein were inherited independently. Anthocyanin pigmentation was associated with head number, seed yield and seed weight; however, striped hull and flower color were not associated with head number, seed yield or seed weight. There was a significant positive correlation between seed yield and head number.

A field experiment conducted for screened 288 elite gen pool of linseed against bud fly infestation at Kanpur, India during rabi 2012-13 to study the bud structure of resistance of linseed against bud fly. The results indicated that the bud length and width showed significant positive correlation coefficient relationship (r=0.1559 and 0.0761) bud infestation. The resistant germplasm line minimum (GS-234) minimum bud length and width (7.93 ×3.26 mm) had relative minimum bud infestation (6.88%) and was statically at par other resistant germplasm lines viz. A-95B, CI-1385, EC-1392, EC-1424, GS-234, IC-15888 and JRF-5. While susceptible germplasm line (Arny) exhibited maximum bud length and width (8.25 ×3. 23 mm) maximum bud infestation(65.11%) which was statically at par with other susceptible lines viz. Ajgan-3-1, Ajgan-20M, Alipur (Hamirpur), Anand, GS-148, GS-440, Gunawal Local, NP(RR)193, RAULD-7810, RLC-28(PM), MS-14, SJKO-2, SJKO-45.

In the present study an attempt has been made to characterize lentil accessions based on qualitative traits. There were variations among 44 lentil accessions. Erect growth habit was observed in 24 % of the accessions where 8% were from Algeria. Conversely, prostrate growth habit was observed in 34% of the accessions. The majority of the remaining accessions (41.32%) were intermediate. Stem with anthocyanin pigmentation was showed in 44% of the accessions, whereas, 56% had no pigmentation (green stem). About half of the accessions had grey green leaves (53%) and 23% of accessions were light green. Among the characters, flower color showed the highest variation. White flowers were observed in 64% accessions and violet flowers were found in 36% accessions. Flowers, with violet stripes in the standard petal (SVE) were observed in 44% accessions and the majority (56%) lacked violet stripes. Yellow cotyledons were observed in 61% accessions, while the rest (39%) had red cotyledons. The majority of accessions (81%) were observed with brown testa while 14% were green and 5% had yellow testa. Absence of seed coat pattern was observed in 69% accessions. However, 8% accessions with spots, 5% with dots, 16% were marbled and the remaining 2% were complex. Flattened seed shape was observed in 60% of accessions. Conversely, globose shape was observed in 40% of the accessions, among of them 27% were from Algeria.

Panicle branching trait of rice is one of the key factors in detemining grain yield. This study was aimed to elucidate the genetic inheritance pattern of the tertiary rice panicle branches trait. Six rice populations i.e F1, F1R, F2, F2R, BC1P1, and BC1P2 generation including parental lines were generated as materials. The experiment was conducted at IPB University, Bogor, Indonesia from April 2017 to February 2019. Several parameters of genetic inheritance was observed. The result revealed that the inheritance of the tertiary panicle branching was controlled by many genes with the high broad-sense heritability and the moderate narrow-sense ones. Based on the scaling test, it was observed that additive dominant model did not fit to the number of tertiary branches and the number of grains of tertiary panicle branches. These phenomenons suspected may due probably to the effect of epistasis. In the advanced analysis employed by using the joint scaling test revealed that the gene action of the number of tertiary branches and number of grains on the tertiary branches were additive and additive×additive.

A set of SSR and RFLP markers for safflower ( Carthamus tinctorius ) and jeweled distaff thistle ( C. oxyacanthus ) was generated from cDNA and genomic libraries and by mining public and proprietary sequence databases. In total, 1412 PCR-based markers and 75 RFLP markers were screened and polymorphic loci were mapped in an intraspecific F2 population of C. tinctorius and an interspecific BC1 population of C. tinctorius × C. oxyacanthus. The two populations shared one common parent and the resulting linkage maps could be compared for synteny. The level of polymorphism was low in both populations and only 8.2% and 13.7% of the analyzed markers could be mapped in the intraspecific and interspecific maps, respectively. The two maps showed significant colinearity of markers in several regions and an apparent translocation or inversion event on one linkage group. Noticeable segregation distortion was found on one linkage group of the C. tinctorius map and dense clustering of loci occurred on several linkage groups of the C. oxyacanthus map. The two maps represent the first major linkage analysis of Carthamus species. The molecular tools will be useful for a variety of genetic and genomic applications in safflower and its related species and have been used in our laboratory to map a flower color gene in C. tinctorius.

Several reports have indicated that oat β-glucans may play an important role in reducing the incidence of degenerative diseases in humans. However, little information has been published on the inheritance of β-glucan concentration in oat. The development of new cultivars with improved β-glucan concentration would be simplified if the mode of inheritance is understood. Three experiments, each using two parental lines and their F1, F2, F3, BC1F2 and BC2F2 generations, were carried out to determine the inheritance of β-glucan concentration. The results indicate that β-glucan concentration is controlled by a minimum of two or three factor pairs with a predominantly additive type of gene action. In the majority of the generations, β-glucan concentration was found to be positively correlated with protein content and negatively correlated with oil content. It was not correlated with grain yield, number of panicles/plant, or number of kernels per panicle. The broad-sense heritability of β-glucan concentration ranged from 0.45 to 0.58 in the F2, and from 0.48 to 0.56 in the F3 generations, suggesting that it may be relatively easy to develop new oat cultivars with high- or low-β-glucan concentration. Key words: Avena sativa, oat, β-glucan concentration, inheritance
