摘要:
在哈尔滨地区对9个杂交粳稻组合材料进行栽培试验，采用灰色关联度分析法对杂交粳稻产量与农艺性状进行关联度分析。结果表明：穗长x4，千粒重x8，株高x1和活动积温x3对产量影响较大；关联度大小顺序为：穗长x4>千粒重x8>株高x1>活动积温x3>穗数x7>穗粒数x5>根干重x2 >结实率x6。说明提高杂交粳稻产量首先应该考虑增加穗长，其次是增加千粒重。选育适宜黑龙江省种植的杂交粳稻需要加强大穗的选择；栽培上要采取提高温度促进杂交粳稻发育的措施。
Abstract:
Nine materials of hybrid?japonica rice were planted in Harbin area,the grey correlation degree analysis was employed to investigate the relationship between yield and agronomic character of hybrid japonic?rice.The results showed that:the main characters such as length x4, thousand seed weighx8, stem lengthx1?and active accumulated temperature x3?had the closer relation with yield;the relative order of yield and agronomic characteristics was length x4> thousand seed weight x8> stem length x1> active accumulated temperature x3> spike number x7> the number of seeds per ear x5> root dry weightx2 > maturing rate x6.Thus,to enhance yield of hybrid japonica? rice should consider the spike length first,then consider increasing thousand seed weight.It needed to strengthen the big spike in the breeding choice to adapt to Heilongjiang area,and enhance the temperature to promote growth of hybrid?japonica?rice in cultivation.
