Genetic variability and association studies of rice (Oryza sativa L.) for iron and phosphorus use efficiency under aerobic condition
Author(s): Ratnakar Manjunath Shet, Rajanna MP and Jagadeesha N
Abstract: Two hundred indica rice accessions were evaluated under aerobic condition for nine traits to examine the nature and magnitude of variability and character association. Among all traits, Iron use efficiency exhibited highest estimate of PCV and GCV followed by grain yield/plant and leaf iron content. Broad sense heritability was highest for 50 percent flowering followed by leaf phosphorus content and straw yield per plant. Association analysis revealed that iron and phosphorus use efficiency had significant positive association with grain yield. Accessions with Contrasting expressions for yield, iron and phosphorus use efficiency were identified for developing suitable rice genotypes under aerobic cultivation.
