COMPARISON OF SOME SELECTION CRITERIA IN TWO SPRING WHEAT CROSSES

Published on

The F2 populations of two spring wheat crosses (WH 283 x WH 280 and NP 846 x WH 291)
were subjected to individual plant selections based on visual appearance for yield
potential, No. of tillers per plant, grain number per spike, l000-grain weight, grain yield
per plant, and harvest index. All the selection criteria were found equal in influencing the
average grain yield of F3 progenies. The effect of selection in F2 generation was not reflected
in F3. Number of tillers per plant and grains per spike showed high correlation with grain
yield per plant. Visual selections based on general plant vigour, number of tillers per plant
and spike length was found to be effective for improving grain yield and its component
traits. The selection based on harvest index produced considerably low proportion of high
yielding lines as compared to other selection criteria.
