Screening of morpho-physiological traits for yield enhancement in a recombinant inbred line population of rice under direct-seeded aerobic and conventional transplanted conditions

Abstract


Direct seeding of rice (Oryza sativa L.) is a resource-conservation technology as it uses water with high efficiency but at the cost of severe reduction in yield. In the present study, recombinant inbred lines (RILs) obtained from a cross between PR 120 x UPLRi 7 were sown as direct-seeded aerobic and conventional transplanted crops respectively for two seasons. Among the various morpho-physiological traits studied, plant height, MTS (Membrane thermo stability) and crop growth rate showed maximum correlation with yield. Plant height and CGR in turn correlated with RGR (relative growth rate).
