Restricted selection in foxtail millet Setaria italica (L.) Beauv.] For yield and nutritional components

Abstract

Restricted selection was used for estimating the genetic advance of yield and nutritional components viz., days to 50% flowering, plant height, panicle length, productive tillers per plant, days to maturity, test weight, protein, carbohydrate, calcium, iron, zinc, copper, manganese, phosphorus and grain yield per plant. The genetic advance of all the fifteen characters under study was estimated by assigning equal economic weights to all characters as well as by using inverse of means as their economic weights. In both cases, the trait plant height recorded maximum estimate of genetic advance in 11 out of 15 cases. The main outcome of the present study is the occurrence of similar trend in the both cases i.e., by assigning equal economic weights and using inverse of means of respective characters as economic weights. This indicates that both ways of assigning weights were equal effective and will result in similar conclusions.
