不同杂交粳稻品种在凉山州的适应性研究

以合系22为对照,对杂粳1、杂粳2、杂粳3、杂粳4、杂粳5进行一年品比试验,研究杂交粳稻相关品种凉山州的适应性以及较对照的增产效果。通过其生育期、农艺性状、产量、变异系数及适应度的方差比较分析并得出结论,以达到因地制宜,筛选高产抗病品种,为品种审定和选用提供科学依据。实验结果表明:杂粳1、杂粳4、杂粳5在产量、性状和适应性方面均比对照合系22好,适宜本地种植。

Adaptive Research on Different Hybrid Japonica Rice Varieties in Liangshan State

The adaptability and Increase yield were studied by yearg compare testing among hybrid keng rice 1, hybrid keng rice2, hy- brid keng rice3, hybrid 4, hybrid 5 and Hexi 22. For the variance comparative analysis on growth period, agronomic traits, yield, co- efficient of variation, the result could provide scientific basis to select high - yielding resistant varieties in special environment. The re- suits showed that hybrid keng rice 1,4, 5 had better performance on yield, Traits and adaptability than Hexi 22, and it was suitable for local growing.
