Genes for late heading and their interaction in the background of Taichung 65



Genes for late heading and their interaction in the background of Taichung 65



Rice genetics II: Proceedings of the Second International Rice Genetics Symposium, 14-18 May 1990: 211-215



Three independent recessive genes for late heading (viz. ef2(t), ef3(t) and ef4(t)) were identified in crosses with this rice variety. The first (formerly called lf1) was identified in a mutant line selected in the M3 of Taichung 65 after X ray treatment (40 krad). It delays heading by about 15 days, conferring some photoperiod sensitivity. The second gene (formerly lf2) was identified in the Philippines variety Inakupa and delays heading by 10 days.
