dc.description.abstract | Pea (Pisum sativumL.) genotypes were evaluated to study variability, correlation, path analysis and genetic divergence. The experiment was laid out in a RBD with three replications. Thirty two genotypes including two check cultivars were evaluated for different horticultural traits. Analysis of variance showed highly significant differences among all the characters under study. Fifteen genotypes viz Palam Triloki, Arka Karthika. Pant Pea-96, Kashi Udai, DPP-3, Pant Pca-86, Kashi Shakti, Pant Pea-74, Palam Priya,PSM- 5, Arka Ajii, Pant Pea-14, VL-12 and Arkcl were superior over other entries and over standard checks for yield, quality and other important horticultural traits. High heritability coupled with high genetic advance as percent of mean were observed for number of rode per plant, plant height, pod yield per plant and pod yield per plot indicating presence of additive gene effects suggesting more scope of selection for these traits. The phenotypic and genoiypic correlation coefficients among different characters showed that yield has positive association with number of branch per plant, number of pod per plant, number of cluster per plant. The path coefficient analysis revealed that, number of pods per plant followed by number of seeds per pod, number of branch per plant, internode length and dry matter content have maximum positive direct effect on pod yield per plant. While, number of cluster per plant, harvest index, shelling percentage, plant height, pod length, days to 50 % germination, number of node per plant and days to 50 % flowering were observed to have negative direct effect on pod yield per plant. These findings indicate that selection may be made on the basis of above mentioned characters for improving yielding ability in the pea. These findings showed that selection should be made on the basis of above mentioned characters for improved yield in pea. Studies on 32 genotypes of pea were grouped into five clusters and maximum number of genotypes was arranged in cluster IV which contained 10 genotypes. All the five clusters showed genetic diversity and the genetic diversity was independent of geographic diversity. Maximum average intracluster distance was found in V and minimum in III. Highest inter cluster distance was recorded between cluster V and II and lowest was observed between cluster IV and III. Indicating that hybridization between genotypes from cluster V and III can be utilized for getting the superior recombinants / transgressive segregants in segregating generations in pea. | en_US |
