Abstract

Analysis of the data revealed significant differences among the genotypes and genotype x
interaction effects for all the characters under study. However, differences among cytoplasm’s was
observed for disease parameters like length and area of the lesion, and agronomic traits like plant
height, agronomic desirability, grain yield plant –1 and test weight. For disease related parameters,
sterile cytoplasm has contributed significantly to resistance for length and area of the lesion. In case
of agronomic traits, fertile cytoplasm has profound dominant effect on agronomic desirability (B-3.4
score/A-3.7 score), grain yield plant-1 (B-33.9 g plant–1 / A-29.8 g plant-1) and test weight (B-2.98 g/
A-2.90g) while sterile cytoplasm exerted profound effect on plant height (A-191.2 cm/
B-194.1 cm) only.
