Abstract
One hundred S0 families selected out of 500 families on the basis of fresh shoot weight were further evaluated for green fodder yield under field conditions. The value of genetic coefficients of variation was found to be high (29.97 %) for green fodder yield per plant suggesting greater variability for the said trait. Green fodder yield had positive and significant phenotypic correlated with number of leaves per plant and plant height. High relative expected genetic advance (18.82 %) was found for green fodder yield than other indicated traits. On the basis of genetic coefficient of variation, inter-relationships and relative expected genetic advance (REΔg %), it is concluded that green fodder weight may be used as selection criteria while selecting superior S1 families of maize. A selection intensity of 20 % from the families revealed an average of 424.2 g compared to 234.6 g green fodder yield. The selected twenty S1 families (out of one hundred families) were inter-crossed to construct a population.
