Mean performance analysis for yield and quality related traits in non-basmati aromatic rice (Oryza sativa L.)

In view to invigorate hybrid rice breeding three CMS lines viz., IR-58025A, CRMS 31A and CRMS 32A and ten rice breeding line/ landraces viz., IET-21842 (R 1536-136-1-77-1), Tulsimongra, Bisni, Gopalbhog, Badshahbhog, Govindphool, Tenduphool, Kumbhdev, Bhatamasuri and Chhinguchi. Altogether 30 crosses were made in LxT mating fashion and evaluated along with one standard hybrid check US 314 (mid early duration) in Randomized Completely Block Design (RCBD) design with 3 replication. Observations were recorded for 29 yield components and quality related traits from five randomly selected plants. Among hybrids, based on mean performance, CRMS 32A X Tenduphool and CRMS 31A X Tenduphool were identified higher yielder. Maximum genetic diversity among parents taken in the study were reported between all lines and testers Chhinguchhi, Kumbhdev and Bhatamahsuri.
