Correlation and path coefficient analysis in bread wheat (Triticum aestivum L.) under timely and late sown conditions

The present experiment was conducted to identify important yield attributing traits under timely and late sowing conditions by employing correlation and path coefficient analysis at Wheat experimental farm, DRPCAU, Samastipur, Bihar during rabi 2020-21. Grain yield plant^-1 had a significant positive correlation with tillers plant^-1, grains spike^-1, chlorophyll content, 1000-grain weight and harvest index under both the conditions, however it reported significant negative correlation with canopy temperature and heat susceptibility index. Whereas, canopy temperature reported significant negative alliance with grains spike^-1 and harvest index under both sown conditions. Analysis of correlations and path coefficients under both sowing conditions indicated that tillers per plant, spike length, grains per spike, chlorophyll content, and harvest index are dependable and efficient traits. These traits not only had a strong positive correlation with grain yield but also showed positive interrelationships and substantial indirect effects on grain yield.
