Abstract
The genetic variability for resistance to Atherigona soccata Rond. in sorghum was assessed in field-plot tests in India in 1979 in the F1 and F2 generations of all possible crosses among 4 tall resistant lines and 4 improved dwarf susceptible lines; there were 3 different levels of infestation with the pest. Seedling mortality and oviposition increased with the shootfly population. The estimates of genotypic coefficients of variability, heritability and genetic advance were higher for both traits when material was tested under optimum shootfly populations. The data indicated that tolerant genotypes could be selected by growing the breeding material under optimum shootfly populations, as indicated by 67-70% seedling mortality and 1-2 eggs/plant on the susceptible standard
