摘要
阐述了协优 5 5 9亲本的生物学特性 ,提出用叶龄余数和幼穗分化进程来预测协优 5 5 9制种的花期相遇 ,安全可靠。总结出3 .75t/hm2
In this paper, the biological characteristics of the parents of hybrid rice Xieyou 559 were described. The forecasting method of flowering time, depending on the leaf age and young panicle differentiation, was present to ensure the safety of seed production. The components of yield structure for 3.75t/hm 2 was summarized.
