STABILITY OF RICE YIELD UNDER DIFFERENT LOWLAND SITUATIONS

Published on Nov 02, 2019 02:56 AM

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.

Keywords: Grain yield, EBT, panicle weight, stability, lowlands.
