Correlation of some varietal characteristics with grain yield and stress tolerance index under saline conditions

Abstract:

Rice production in saline soils could be increased if salt-tolerant genotypes were developed, but progress toward combining superior tolerance with good yield potential is slow, largely because of the nonavailability of reliable and efficient selection criteria. Selecting directly for grain yield under saline conditions may be limited by the low heritability of observed variation and failure to distinguish between yield potential and capacity to cope with adverse stress factors.
