摘要
为筛选适宜寒地水条播栽培的水稻品种,明确水条播栽培下水稻农艺性状及品质性状适应性评价指标,以29份寒地早粳稻为材料,采用随机区组试验设计,利用水条播适应系数、适应指数和综合适应能力,结合主成分分析对水稻条播适应性进行综合评价。结果表明:能同时在水条播适应系数、适应指数以及综合适应能力上均表现为高度适应的材料共3份。穗粒数、成粒率、经济系数、千粒重和理论产量5个因子可作为水条播下水稻农艺性状适应性评价指标;整精米率、垩白度、精米粒长、直链淀粉含量和米饭食味评分5个因子可作为寒地水条播下水稻品质性状适应性评价指标。
In order to screen rice varieties suitable for sowing in line under water cultivation in cold regions and clarify the adaptability evaluation indexes of agronomic and quality traits of sowing in line under water cultivation,29 early japonica rice varieties in cold regions were used as materials,and random block experiment design was adopted to comprehensively evaluate the adaptability of sowing in line under water cultivation by using sowing in line under water adaptability coefficient,sowing in line under water adaptability index and comprehensive adaptability,combined with principal component analysis method.The results showed that there were 21 materials that can satisfy the adaptability coefficient,adaptability index and comprehensive adaptability of sowing in line under water simultaneously.Five factors including grain number per panicle,grain formation rate,economic coefficient,1000-grain weight and theoretical yield can be used as adaptability evaluation indexes of rice agronomic traits under sowing in line under water.The five factors of head rice rate,chalkiness degree,grain length,amylose content and rice taste score can be used as adaptability evaluation indexes of rice quality traits under sowing in line under water in cold region.
