STABILITY OF RICE YIELD UNDER DIFFERENT LOWLAND SITUATIONS

Published on

Phenotypic stability was studied in 47 rice genotypes under four different lowland
situations for grain yield and its two important components,panicle weightand ear bearing
tillers (EST) perhill. Significantgenotype (G) x environment(E) interactionswere observed
for all the traits. Among the linear and nonlinear components of G x E interaction, linear
component was predominant for EBTlhill and nonlinear component for grain yield, while
both are equally important for panicle weight. On the basis of stability parameters, the
genotypes CR 728-7-2·2, CR 673-431 and Utkal Prava were identified as best cultures for
both intermediate and semi-deep low land situations under direct seeded as well as
transplanted conditions.
