Notes:
Four cold-tolerant rice varieties, viz. ‘Khonorullo’, ‘Namyi’, ‘Abor B’ and ‘Meghalaya-1’ were crossed with two cold-susceptible ones, viz. ‘Pusa 33’ and ‘Subhadra’ (DR92), in all possible combinations to study the inheritance of gene(s) governing panicle exsertion and their allelic relationship among cold-tolerant varieties. F1 hybrids of all the crosses showed complete panicle exsertion indicating dominance of this trait. Segregation pattern of panicle exsertion in F2 and backcrosses show that all the four cold-tolerant varieties possessed a single dominant gene designated as Ctr-1. Absence of segregation for panicle exsertion in an F2 generation obtained from intercrosses of cold-tolerant varieties suggests that the dominant genes in all the four cultivars are allelic.
