摘  要:
Combinations of early hybrid rice Zhong 9A/R12,Zhong 9A/R37, Jin 23A/R8, Zhu S/R36 and Jinyou 463 (CK) were used in the comparison test.Leaf shooting speed, tiller dynamics, yield components, yield and agronomic traits were analyzed.The results showed that the combination 9A/ R37 had the highest yield of 7 231.5 kg/hm2, 4.80% higher than CK.It had a good comprehensive performance with high yield potential, and could be demonstrated in larger area in central and northern region of Guangxi province.
