| 摘 要： | 灌浆期遭遇低温是影响湖南晚稻生产的主要气候因素.采用分期播插试验,将6个C两优和6个Y两优母系组合对秋季低温的抗性进行了比较.试验结果表明:不同组合对2010年9月下旬至10月上旬多日持续低温的抗性存在显著差异；Y58S系组合对后期抗低温抗性比C815S系列组合较强,主要表现在Y系组合高产性、结实性均优于C系组合；而Y...

| Abstract: | Low-temperature appeared at grain filling stage was one of the major climatic factors that affect late rice production in Hunan province.Using stage sowing and transplanting experiment to compare the low-temperature resistance in autumn among six combinations of Cliangyou and six combinations of Yliangyou.The results showed that the resistance of different combinations to a continuous low-temperature lasted from late Sep.to early Oct.2010 had significant different;the resistance to low-temperature of Y58S c... |
