Selection of S1 Maize (Zea mays L.) Families to Develop High Green Fodder Yielding Population
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.
