The present study was aimed at finding out the nature and magnitude of genetic variability and association studies in segregating population of the field pea for grain yield and other yield component traits to select the transgressive segregants for further breeding programme. Twenty F₂field pea plant population were grown in Randomized Block Design (RBD) with 3 replications to assess the variability and association patterns for the characters under study. Significant differences were observed among all the F₂plants for all the characters studied, except for days to emergence. Moderate to high heritability (broad sense) coupled with moderate genetic advance as percent of mean was recorded for the characters plant height, pod length and 100 seed weight indicating role of additive gene action in the expression of these traits. Numbers of pods per plant, plant height, number of primary branches per plant, 100 seed weight and number of clusters per plant were the major characters contributing to grain yield as these traits were significantly and positively associated with grain yield per plant. Number of pods per plant recorded highest positive direct effect on grain yield per plant via positive indirect effects of plant height and number of primary branches per plant.

Its a very nice paper. I am also working in a project using RBD Methods
