Abstract:
During Kharif 2020, twenty-two rice genotypes were assessed for quality-attributing attributes at a Banaras Hindu University (BHU) agriculture research farm. For quality traits like kernel length, kernel breadth, l:b ratio of the kernel, l:b ratio of the cooked kernel, aroma, and elongation ratio, statistical analysis was used to assess genotypic coefficient variation (GCV), phenotypic coefficient variation (PCV), broad-sense heritability, and genetic advance as a percentage of the mean (GAM). For the various characters under investigation, analysis of variance, GCV, and PCV demonstrated significant variation. While kernel length had a substantial positive correlation relationship with the l/b ratio and after cooking kernel length, it had a significant negative relationship with the elongation ratio. Positive and direct effects were found for kernel length, kernel breadth, l/b ratio of the kernel, and elongation ratio among all the characters studied through path analysis, while Negative and direct effects were found for amylose content, kernel length after cooking, kernel breadth after cooking, and l/b ratio of the cooked kernel. Sik Nadiya, Gundari Bhog, Kapoor Bhog, Jeera Phul, Rani Manger, J R 32, Kalanamak Bhu, Chak Hao Angoubi-4, and Govind Bhog 5 genotypes were identified as having strong aroma.
