Abstract

The objective of this study was estimate the response to individual plant selection in early generation through direct and indirect selection for increased grain yield was carried out. The selection intensity of 10 % approximately was used with direct selection of yield and with indirect selection using yield components in wheat, i.e. number of spikes per plant, number of kernels per spike and 1000-kernel weight in gm. In 2009/2010, promising lines in F5 for each criterion were evaluated under flood irrigation at the Sids Agricultural Research Station conditions, Agricultural Research Center, Egypt. The high selected lines (20 lines) from direct and indirect selection for high yielding for each criteria (grain yield/plant "direct selection", number of spikes per plant, number of kernels per spike and 1000-kernel weight in gm "indirect selection") and the two parents also, two checks (Sids 12 and Sids 13) were evaluated in nested design with three replications in each population. In the first population, the selection of high number of grains/spike gave the highest grain yield/plant. In the second population the selection of high number of spikes/plant gave the highest grain yield/plant. The results indicated that selection for indirect selection was more efficient in breeding for word superior yielding F5 lines.
