Genetic Coefficient of Variation, Relative Expected Genetic Advance and Inter- relationships in Maize (Zea mays L.) For Green Fodder Purposes at Seedling Stage
Syed Sadaqat Mehdi and Muhammad Ahsan

Abstract: Five hundred S1 families were evaluated in the greenhouse for seedling traits in C1 recurrent selection cycle. Higher values of GCV% were toand for fresh shoot and dry root weight (28.85 and 41.95 respectively). Moderate broad-sense rieritahility (h2BS) estimates were found for fresh shoot weight, dry root weight and fresh shoot length (42.45, 48.94 and 55.0 respectively). Fresh shoot weight was phenotypically, highly significantly and positively correlated with other indicated traits. Hign values of coefficients of variation, positive highly significant inter-relationships, moderate broad-sense heritability (h2BS) estimates and relative expected genetic advance (REΔg %) was also found greater for fresh shoot weight and dry root weight. It is generally concluded from the results that fresh shoot weight can be used as selection criteria while comparing S1 families at seedling stage in maize as it is easy to determine as compared to dry root weight.
