Investigation of correlation between traits and path analysis of rice (Oryza sativa L.) grain yield under coastal salinity

Abstract

Correlation and path analysis was carried out to study the association between quantitative traits on yield of rice. Grain yield per plant exhibited positive and significant association with number of productive tillers, panicle length, number of grains per panicle, grain breadth and hundred grain weight suggesting that selection pressure applied for these traits will eventually increase the grain yield per plant under salinity. The secondary trait panicle length showed significant positive association with number of grains per panicle, hundred grain weight and grain yield, suggesting that selection based on this trait will be fruitful for enhancing grain yield.
