dc.description.abstractABSTRACT The present investigation entitled “Studies on Genetic Divergence in Pea (Pisum sativum L.)” was conducted at Vegetable Farm, Department of Vegetable Science, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Rabi, 2017 to evaluate genotypes of pea and to study variability, heritability, correlation and path analysis of different characters along with estimation of genetic divergence among genotypes. The experiment was laid out in RCBD with three replications and 35 genotypes including one check variety “Pb-89”, for studying the extent of variability and performance of each genotype. The present studies revealed a significant difference among genotypes for all the characters studied. A wide range of variability was observed for all the traits. Genotypes like Pusa Pragati, UHF-PEA-15, UHF-PEA-12 and EC 598536 were significantly superior over other genotypes and the check variety for yield and few other horticultural important traits and can be recommended as such for direct cultivation after multilocational testing in the state. The GCV and PCV were high to moderate for traits like green pod yield per plant, pod weight, pod length and plant height. High heritability coupled with high to moderate genetic gain was observed for green pod yield per plant, pod weight, pod length and plant height which suggests their improvement through simple selection method. Correlation analysis revealed that traits like number of green pods per plant, pod weight, pod length, pod width, pod girth, number of seeds per pod and shelling percentage had significant positive correlation with green pod yield per plant both at phenotypic and genotypic level. Further, path coefficient analysis indicated that pod weight had the highest positive direct effect on green pod yield per plant followed by days to marketable maturity, number of green pods per plant and number of seeds per pod. Therefore, main emphasis should be given on these characters, while making selection in pea genotypes. D2 Mahalanobis analysis divided the genotypes into six clusters and revealed that the cluster III and IV were most divergent and there will be more chances of getting better segregants in F2 and subsequent generations from the crossing of genotypes from cluster III and IV. Thus, hybridization between the genotypes of these groups can be very effective for further improvement inpea.en_US
