Estimation of Correlation and Path Association in Hexaploid Wheat (Triticum aestivum L.) with the Feasibility of Developing F1 Hybrid in Half Diallel Mating Design

Abstract

The present study was carried out at Mata Gujri College, Fatehgarh Sahib’s Experimental Farm, Department of Agriculture, Punjab during2019-20, and 2020-21. The experimental material consisted of six parental varieties (HD 1981, PBW 343, CPAN 3004, RAJ 2184, PBW154, and PBW 65) collected from the Indian Institute of Wheat and Barley Research (IIWBR) New Delhi, India and their 15 F1s obtainedfrom half diallel mating design were grown in Randomized Block Design. The association studies among different characters showedthat grain yield per plant had a significant positive correlation with no. of grain per plant, that can be successfully used for the geneticimprovement of seed yield in bread wheat.
