Abstract
To study the correlation and path coefficient analysis between yield and its contributing traits, an experiment was carried out with 60 bread wheat genotypes under late sown conditions during Rabi 2017-18. Data of contrasting traits viz. days to 50 per cent heading, days to anthesis, canopy temperature at heading and after anthesis, grain growth rate 14, 21 and 28 days after anthesis, plant height, peduncle length, peduncle extrusion, number of effective tillers m-1, spike length, spikelet spike-1, no. of grains spike-1, 1000 grain weight, biological yield plot-1, harvest index and grain yield plot-1 were analysed. The results revealed that grain growth rate at 14 days after anthesis, effective tiller m-1, spike length, grains spike-1, biological yield plot-1, 1000 grain weight and harvest index were positive and significantly correlated with grain yield plot-1 with highest direct and positive effect on grain yield plot-1 via biological yield plot-1 followed by harvest index.
