| Abstract: | We constructed a near isogenic line of rolled leaf gene Rl(t), which expressed incompletely dominance for the character of rolled leaf(RL), with genetic background of Zhenshan 97B. Using RL Zhenshan 97B and the original Zhenshan 97B as the female parents,and Minghui 63 and Yanhui 559 as the male parents, crosses of RL Shanyou 63 (RS63) and Shanyou 63(S63), RL Shanyou 559 ( RS559) and Shanyou 559 (S559) were made. Inheritance and effects of Rl(t) in hybrid rice were studied at the flowering and at the 20 d after flowering, respectively. Results were as follows: |
