Variability in 66 accessions of faba bean (Vicia faba L.) was assessed for different agro-morphological and quality parameters. Variability parameters, correlation coefficients, clustering and PCA were performed for yield and its contributing parameters. A very good variability was found in number of branches per plant ranged from 5.4 to 14.4, number of nods per main branch from 10.22 to 26.31, no. of pods in main branch varies from 8.61 to 19.65, 1000-seed weight from 271.69 to 390.31and seed yield per plant varied from 31.32 to 100.3.The protein content (%) of the genotypes varies widely from 26.31 to 31.52.Positive and significant correlation coefficients were also obtained between grain yield and 1000-seed weight (r = 0.33**) and number of pods in main branch (r = 0.01*). Principal Component Analysis shows that PC5 explained 62.8% of the total variance and was most closely associated with number of pods per cluster.

Experiments involving the intercropping faba bean with each of lupin, fenugreek and Egyptian clover as well as growing faba bean alone were carried out at Assiut University on a farm naturally infested with Orobanche in two seasons. The major objective of the study was to investigate the effect of different intercropping combinations with faba bean on the infestation with Orobanche. The results obtained revealed that intercropping faba bean with each of lupin, fenugreek and Egyptian clover markedly reduced the Orobanche crenata Forsk infestation of faba bean. the number of branches, the height of the first pod, the number of pods, the seed yield and the number and dry weight of Orobanche spikes were significantly affected by the intercropping treatments, but these had no significant influence on plant height, straw yield or 100-seed weight. intercropping faba bean with each of lupin, fenugreek and Egyptian clover increased the faba bean seed yield, consequently the economic return was also increased.

Sulphur is increasing and after nitrogen, phosphorus and potassium is forth important macro nutrient. In this study three sources of sulphur i.e., Gypsum, Elemental sulphur and Potassium Sulphate with three levels i.e., 40, 70 and 100 kg S ha-1 for each source were tried. The pooled data showed sulphur from potassium sulphate recorded the lowest days to first flower (246), days to 75% seed maturity (328.1), and highest number of branches plant-1 (35), number of siliqua plant-1 (709.5), 1000 seed weight (3.87g), seed count siliqua-1 (20.8), seed yield plant-1 (12.9 g), seed yield hectare-1 (4.8 q), highest Dry matter (9.6 g), TSS (7.6oBrix), Crude protein (20.6%), head compactness (0.032) and oil content (29.7%). Application of increasing levels of sulphur up to 100 kg ha-1 significantly increased the seed yield contributing characters in cabbage as lowest days taken to first flower (250.8), lowest days to 75% seed maturity(334.1) and highest number of branches plant-1 (31.7), siliqua plant-1 (671.60), seed count siliqua-1 (17.9), 1000 seed weight (2.6g), seed yield plant-1 (11.90 g) and seed yield hectare-1 (4.4q ) whereas, among quality parameters highest vitamin C (59.1 mg/100), dry matter weight (9.0 g), Crude protein (18.3), and Head compactness (0.026) were recorded with sulphur application of 70 kg ha-1.

Chickpea (Cicer arietinum L.) is the second most important food legume crop after common bean (Phaseolus vulgaris L.). It is one of the most important rabi pulse crop in India and contributes to 20% of the total pulse production in the world. India ranks first in chickpea production in the world followed by Australia, Myanmar and Pakistan. It is one of the major pulse crops in Bihar. The present investigation was undertaken using forty genotypes of desi chickpea sown in a randomized block design with three replications at the Pulse research model Bhitti farm of Bihar Agricultural University, Sabour (Bhagalpur) during Rabi, 2016-17 to determine the contribution of six morphological traits to the total variability in desi chickpea using Principal component analysis. In the present investigation PCA was performed for six quantitative traits of chickpea. Out of six, only 2PCs exhibited more than 1.0 Eigen value and showed about 79.86% variability. Therefore, these 2 PCs were given due important for the further explanation. The PC1 showed 28.96% variability among traits, while PC II, PC III and PC IV exhibited 21.93%, 16.35% and 13.87% variability respectively.PC1 contributed 28.96% of the total variation and correlated with days to 50% flowering, days to maturity and 100-seed weight while PC2 explained an additional 21.93% of the total variation and dominated by plant height, grain yield per plot, days to maturity, days to 50% flowering and number of pods per plant. Since, a total of 50.91% of the total variation was contributed by PC1 and PC2, therefore, these two principal components can be allowed for simultaneous selection of yield contributing traits in desi chickpea. Genotype commonly found in more PC, were KWR108, JG2016-44, Sabour chana-1, IPC 2013-21, HI12-63, AKG1303, PG214J and RKG13-380. Similar type of genotypes on a common principal component permitting to designate them as seed yield factors. These genotypes may further be utilized in breeding programmes for improving seed yield and these genotypes can be considered an ideotype breeding material for selection of traits viz. more total number of seed per plant and 100-seed weight further utilization in precise breeding programme.

The present study was conducted to evaluate 44 greengram genotypes using correlation, path analysis, principal component analysis and cluster analysis based on ten morphological traits. Basic descriptive statistics showed considerable variance for all the traits. Association analysis indicated that, number of pods per plant, number of pod clusters per plant, number of seeds per pod and number of branches per plant showed significant positive association with seed yield per plant. Path analysis specified that the highest positive direct effect on single plant yield was exerted by days to 50 % flowering, number of pods per plant and number of seeds per pod. Principal component analysis (PCA) revealed 79.12 per cent of the variability by the first five components. PC1 was associated mainly with seed yield per plant, number of pod clusters per plant, number of pods per plant and number of branches per plant. The Wards method of hierarchical cluster analysis grouped the accessions into six major clusters. The clustering of greengram genotypes based on different morphological traits would be useful to identify the promising genotypes for effective utilization in future breeding programmes..

Genetic variation in cucumber accessions from China was assessed by examining variation at 21 polymorphic isozyme loci. Principal component analysis of allelic variation allowed for the depiction of two distinct groupings of Chinese accessions collected in 1994 and 1996 (67 accessions). Six isozyme loci (Gpi, Gr, Mdh-2, Mpi-2, Pep-gl, and Pep-la) were important in elucidating these major groups. These groupings were different from a single grouping of Chinese 146 accessions acquired before 1994. Allelic variation in Chinese accessions allowed for comparisons with other accessions in the U.S. National Plant Germplasm System (U.S. NPGS) collection grouped by continent and sub-continent. When Chinese accessions taken collectively were compared with an array of 853 C. sativus U.S. NPGS accessions examined previously, relationships differed between accessions grouped by country or subcontinent. Data indicate that acquisition of additional Chinese and Indian cucumber accessions would be strategically important for increasing genetic diversity in the U.S. NPGS cucumber collection.

19 Groundnut ( Arachis hypogaea L. ) genotypes receiv ed from International Crops Research Institute for Semi Arid T ropics (ICRISA T) India w ere ev aluated in a non replicated trial and the characters w ere subjected to multiv ariate analysis to study the v ariability within the genotypes. The first 5 axes of the principal component analysis captured 78% of the total v ariability and identified yield parameters such as number of pods per plant, pod w eight per plant and growth parameters such as number of branches per plant, plant spread, and pod characteristics as the characters contributing most to total v ariation. Phenotypic correlation analysis rev ealed that the yield has positiv e correlation with the characters such as number of pods per plant and number of branches per plant. W ards clustering method has grouped the genotypes into 3 distinct clusters. The results can be applied in order to strengthen the breeding program

Auxin not only controls the development processes, but also regulates the stress responses of plants. In this investigation, we explored the potential roles of exogenously applied indole-3-acetic acid (IAA) in conferring salt tolerance in the faba bean (Vicia faba L.). Our results showed that foliar application of IAA (200 ppm) to salt-exposed (60 mM and 150 mM NaCl) plants promoted growth, which was evidenced by enhanced root–stem traits. IAA application ensured better osmotic protection in salt-stressed plants which was supported by reduced proline and enhanced soluble sugar, soluble protein, and total free amino acid contents in the roots, stem, and seeds. IAA application also increased the number of nodules in salt-stressed plants, which may facilitate better nitrogen assimilation. Moreover, IAA mediated improvements in mineral homeostasis (K+, Ca2+, and Mg2+) and the translocation of Na+, while it also inhibited excessive accumulation of Na+ in the roots. Salt-induced oxidative damage resulted in increased accumulation of malondialdehyde, whereas IAA spraying relegated malondialdehyde by improving antioxidant enzymes, including superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase. Together, these results together with a principal component analysis uncovered that foliar spraying of IAA alleviated the antagonistic effects of salt stress via enhancing osmolyte accumulation, ionic homeostasis, and antioxidant activity. Finally, exogenous IAA enhanced the yield of broad beans under high salinity conditions.
