Restriction selection Indices in foxtail millet [Setaria italica (L.) Beauv.] using equal economic weights and inverse of means

Restricted selection was used for calculating 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 fifteen characters studied was calculated by assigning equal economic weights to all of them as well as by using the inverse of means as their economic weights. In 11 of the 15 cases, the trait plant height showed the highest estimate of genetic advance in both cases. The key finding of this analysis is that identical trend exists in both cases i.e., by assigning equal economic weights and when inverse of means of respective characters are used as economic weights. This indicates that both methods of assigning weights were equally effective and will result in similar conclusions.
