Association studies for yield components and dormancy related traits in rice (Oryza sativa L.)

Abstract

One hundred and nineteen recombinant inbred lines along with parents BPT 2231 and MTU 1001 were studied to determine the association between yield, yield components and dormancy related traits. The results revealed that total soluble sugars and free amino acids manifested positive and significant relationship with germination (%) at 5 days and 10 days after harvesting. Grain yield per plant exhibited significant & positive relationship with test weight while its association with total soluble sugars is significant and negative. The studies of path analysis revealed maximum direct effect for germination (%) at 10 days after harvesting followed by test weight.
