Interrelationships among yield and its contributing traits in rice (Oryza sativa L.) under sodic soil

Abstract

The experiment was conducted to work out the correlation and path coefficient effects of their various attributes on grain yield in rice with 110 genotypes (aromatic and non-aromatic rice) along with three check varieties viz., Sarjoo 52, FL 478 and CSR 10 of rice. The grain yield per plant exhibited a highly significant and positive correlation with biological yield per plant (0.8993), followed by spikelets per panicle (0.5563), grains per panicle (0.5522), panicle length (0.4187), flag leaf area(0.3844) and leaf nitrogen (0.3187), while significant and positive correlation was recorded with spikelets fertility (0.1765). The highest positive direct effect on grain yield per plant was exerted by biological yield per plant (1.1186) followed by the harvest index (0.4738). Therefore, these characters emerged as most important interrelationships of grain yield in rice.
