10 bread wheat genotypes were crossed in diallel fashion excluding reciprocals. The F1s and the parental lines were then utilised for combining ability analysis. Analysis of variance (ANOVA) showed the presence of significant variation for all four quality traits. ANOVA showed highly significant estimates of mean square for general combining ability for sedimentation value, hectolitre weight and phenol colour reaction however for protein content it was significant. Mean square for specific combining ability was highly significant for sedimentation value and phenol colour reaction while for protein content and hectolitre weight it was nonsignificant. | 2020 9 2 929-938 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 9 Number 2 2020 Journal homepage http Original Research Article https Genetic Analysis of Quality Traits in Bread Wheat Anjali Joshi Anil Kumar Vartika Budhlakoti and Nidhi Bhatt Department of Genetics and Plant Breeding College of Agriculture Govind Ballabh Pant University of Agriculture and Technology Pantnagar .

The F1s and the parental lines were then utilised for combining ability analysis. Analysis of variance ANOVA showed the presence of significant variation for all four quality traits. ANOVA showed highly significant estimates of mean square for general combining ability for sedimentation value hectolitre weight and phenol colour reaction however for protein content it was significant. Mean square for specific combining ability was highly significant for sedimentation value and phenol colour reaction while for protein content and hectolitre weight it was nonsignificant. Parental line UP 2762 KFA 2 KACHU and Raj 4419 showed superior general combining ability for more than one quality traits. On the basis of high per se performance and significant SCA effects in desired direction Raj 4419 x PBW 729 KAUZ ALTAR84 3 MILAN KAUZ 4 HUITES x UP 2762 PBW 729 x DBW 50 and Raj 4419 x NIAW 1594 were identified as superior cross combiners for protein content sedimentation value hectolitre weight and phenol colour reaction. These crosses can therefore be exploited commercially either in development of hybrid varieties with improved quality traits or in recovery of superior transgressive segregants which can be .
