摘要
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。
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.
