Path Analysis In Rice ( Oryaa sativa Linn. )

Abstract

When biometrical studies on forty divergent varieties of lndlea rice (Oryza satlva L.) were conduoted at the College of Agriculture, Vellayanl under tbe Kerala Agricultural University during June - September 1977, the estimates for genotypic correlation of yield and eight components, aad path co-efficient of yield aad the first, second aad third orders of components revealed that relatively short 3tatured plants having more number of panicle bearing tillers, and more number of heavier grains on relatively shorter panicles, preferably with a few primary branches, have been found to be ideal for a type having high grain yield potential. Therefore, it Is recommended that selection for high grain ylelders in this crop should be based on these criteria.'
