Character association and path analysis of yield contributing traits and quality parameter in rice (Oryza sativa L.)
Author(s): Satya Prakash, KK Srivastava and RDS yadav
Abstract: Fifty six genotypes including four check varieties of rice (Oryza sativa L.) were assessed to work out the association of different seed yield traits, direct and indirect effects of their various attributes on seed yield. Seed yield per plant showed significant and positive correlation with seed yield per plant showed highly significant and negative correlation with days to plant height and non-significant correlation with other characters. The characters showing significant positive correlation among yield and important characters would be highly effective and efficient in improving respective traits. Path analysis identified as important components having high order of direct effect to secondary branches per plant and vigour index as important components having high order of indirect effect on seed yield per plant. The characters identified above as important direct and indirect yield components merit due consideration in formulating selection strategy in rice for selection of high yielding varieties.
