The present study entitled “Genetic Divergence in Black gram [Vigna mungo (L.) Hepper]” was conducted with 56 genotypes and two checks namely Pant U-31 and Pratap Urd-1during Kharif- 2019 at the Experimental farm, RCA, MPUAT, Udaipur. The genotypes were planted in augmented RBD design in four blocks. Mean squares due to genotypes were significant for plant height, number of branches per plant, number of pods per plant and pod length out of twelve characters as divulge from ANOVA.

Thirty mungbean genotypes were evaluated for the estimation of genetic variability, heritability, genetic advance, correlation coefficient, and path coefficient analysis for yield and its component traits. A considerable amount of genetic variability was observed among all the genotypes for all the characters under study. GCV & PCV were highest for seed yield per plant, followed by harvest index, biological yield and number of pods per plant.

The study revealed highly significant differences for all the yield and its contributing traits, indicating the presence of high genetic variability. The phenotypic and genotypic co-efficient of variation (PCV and GCV) was high for grain yield per plant followed no of productive tiller per plant and moderate for plant height, spike length and thousand grain weight.

Variability studies were carried out for different characters of groundnut derived from four crosses viz., Kadri-9 x GPBD-4, ICGV-00351 x GPBD-4, Kadri-9 x Sunoleic-95R, ICGV-00351 x Sunoleic-95R. Results revealed that the presence of moderate to high PCV and GCV for most of the traits, further a high heritability coupled with high genetic advance was also observed for these traits indicating the involvement of additive gene action in controlling these traits making selection effective.

The extent of variability and heritability of the characters among the genotypes is the basic source for the exploitation of superior potentiality of genotypes. Calculation of GCV and PCV will gives the extent of environmental influence on the traits, whereas heritability gives the information on the magnitude of inheritance of quantitative traits, while genetic advance will be helpful in formulating suitable selection procedures.

Thirty basmati rice genotypes were evaluated in RBD with three replications with an objective of assessing the genetic variability, heritability, genetic advance for twenty-two yield and quality characters. The results of ANOVA revealed that the mean sum of squares among the genotypes for all the characters were highly significant indicating the presence of ample amount of variability which can be exploited for selection of characters for crop improvement programme.

Genetic variability, heritability, correlation and path analysis were estimated among 59 accessions of 08 quantitative characters in durum wheat. The highest value of GCV and PCV were observed for grain yield per plot, tillers per meter row length, spike length, grains per spike and test grain weight. It is also observed that the traits like grain yield per plot, tillers per meter row length, grains per spike and test grain weight exhibited high GCV also possesses high genetic gain indicating preponderance of additive gene effect for these traits.

Twenty one genotypes including check Krishna were evaluated in randomized block design with three replications during kharif-2017 at research farm of TCA, Dholi for estimation of genetic variability among them. Genotypes varied significantly for all the morpho-physiological characters indicating the presence of considerable variability among the genotypes. Significant bidirectional shift was observed in the mean values as compared to better check, thus provided scope for selection.

An investigation was undertaken to evaluate forty three progenies from F5generation of Lablab bean along with one local check for estimation of genetic variability, heritability and genetic advance. A wide range of variation was observed for yield and its component traits among the progenies under study. Highest and lowest coefficient variation was noticed in the seed yield per plant and days to maturity respectively.

The present investigation was carried out to study the magnitude of genetic variability, correlation and path coefficient among 20 traits in ten amaranthus accessions belonging to Amaranthus tricolor. Comparison of genotypic co-efficient of variation (GCV) and phenotypic co-efficient variation (PCV) for different traits indicated that the values of PCV were higher as compared to GCV due to the influence of environment. High GCV and PCV were observed for leaf length, leaf breadth, stem weight, seed yield per plant and anthocyanin content.
