Revealing genetic variation in local upland rice germplasm collection of Odisha
AbstractWide array of genetic variation was observed for agro-economic traits among a set of 96 land races. Bhogi revealed short plant stature and it took just 78 days to mature. Khursudi and Asumakunda revealed high yield potential, while Salampikit, Kalakeri, Browngora, CR Dhan 40 and N22 were identified to have high degree of drought tolerance. Considering both leaf area and chlorophyll index; Kinari and Setka-1 had significantly higher value indicating efficient photosynthesis under water stress. Salampikit and N 22 were identified to be nearly free from BLB (0.8-1.0 score) whereas, almost all other genotypes showed moderate to high susceptibility. High tillering capacity (Harisankar, CR Dhan 143-2-2, Kinari, Hiran, Badi and Kutiarasi), longer panicle (Kantadumer, Rasakadali , Damaraphuli, Padarabank, Somo , Asumakunda and Anjali), heavy panicle (Sarian, Dhobasaria, and Anjali), and more number of grains per panicle (Padarabank, Pustak and Pankopoat) were recorded in few landraces. Dhanisaria, Kanding and Dhubasaria recorded significantly higher percentage of grain fertility. Chinger-2 had very bold grains and popular upland varieties e.g., Khandagiri, Vanaprabha and Mandakini revealed higher grain and kernel length.
