Abstract

The WHEAT APHID/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> RUSSIAN WHEAT APHID (RWA), Diuraphis noxia (Mordvilko), is a significant insect pest of WHEAT worldwide. The objective of this study was to assess the GENETIC VARIATION within and between F2-derived families for reaction to RWA using F3 and F4 families originating from individual F2 plants of a cross between the susceptible line (synthetic hexaploid-11) and the resistance cultivar (‘Halt’). The RWA damage of individual plants within each family was measured using different procedures. Their reaction types were combined into a single data for each individual family (derived from an individual F2 plants) and subjected to statistical analysis. Results indicated that the GENETIC VARIATION between F2-derived families is greater than within F2-derived families for RWA resistance. Broad-sense HERITABILITY of RWA resistance, calculated by partitioning phenotypic variation into genetic and environmental components, was 73.2%. A narrow-sense HERITABILITY estimate of 30% was obtained for the RWA resistance in the ‘Halt’ × synthetic hexaploid-11 cross using parent-offspring (F3: F4) regression procedure.
