Abstract

A diallel cross study comprising of ten bread wheat (Triticum aestivum L.) cultivars were carried out with its parents and F1 progeny for correlation coefficient and path coefficient analysis of yield and its attributes in wheat. The present investigation revealed that grain yield was positively correlated with biological yield plant-1 , effective tillers plant-1 , number grains plant-1 , number of spikes plant-1 , harvest index, number of spikelets spike-1 , plant height and number of grains spike-1 . However, path analysis strongly pointed out the role of days to maturity, plant height, number of grains spike-1 , number of spikes plant-1 , biological yield plant-1 , harvest index and 1000 grain weight in the determination of grain yield per plant. Hence, more importance should be given to these traits while exercising selection. Based on correlation and path studies it was reported that biological yield plant-1 , number of spikes plant-1 , harvest index, plant height, effective tille

Conclusion

The present investigation revealed that grain yield was positively correlated with biological yield/plant, effective tillers/plant, number of grains/plant, number of spikes/plant, harvest index, number of spikelets/spike, plant height, days to flowering and number of grains/spike. However, path analysis strongly pointed out the role of days to maturity, plant height, number of grains/spike, number of spikes/plant, biological yield/plant, harvest index, 1000-grain weight and wet gluten in the determination of grain yield/plant. Hence, more weightage should, therefore, be given to these traits while exercising selection. Based on correlation and path studies it was reported that biological yield plant-1, number of spikes plant-1, harvest index, plant height, effective tillersplant-1 and number of spikelets spike-1 could be used as important selection traits in order of merit to improve productivity during designing of suitable breeding programme in wheat.
