tailieunhanh - Study of path analysis to access the direct and indirect effect of yield improving components in rice (Oryza sativa L.) under sodic soil

This research was conducted at main experiment station of . &T. Kumarganj, Ayodhya (.) in rice growing season during 2015- determine the direct and indirect effect of yield improving component on yield improvement. The material consist of 21 hybrids (F1) developed through crossing 7 lines with 3 testers. Path analysis shows that harvest index, followed by spikelet fertility, biological yield per plant, panicle bearing tiller per plant and plant height are most important direct yield contributing component while harvest index followed by 1000- grain weight and spikelet fertility appeared as most important indirect yield components. | Study of path analysis to access the direct and indirect effect of yield improving components in rice (Oryza sativa L.) under sodic soil
