Abstract

The experiment was conducted during two successful winter seasons of 2021/ 2022 and 2022/2023 at the Research Farm of the Faculty of Agriculture, Sohag University. Three F3 and F4 segregated Peas populations were used; population one derived from (Cash x Sweet1), population two derived from (Sweet1 x Sweet2) and Population three derived from (Progress x Sweet2); to estimate the genotypic and phenotypic correlation values between ten studied traits. The estimated values of genotypic correlation between most of the studied traits were higher in values than their phenotypic correlation values, this implies, a strong relationship in different pair of characters. The genotypic and phenotypic correlation values among plant dry seed yield and other traits like height of plant, plant branches number, plant pods number, length of pod, pods weight and pod filing percentage was highly significant and positive. Thus, these traits found as most vital component characters and associated positively with plant dry seed yield.
