摘要:

为探究水稻不同农艺性状对产量的影响,并初步筛选适宜种植的优良连作籼粳杂交晚稻品种,采用灰色关联分析对16个供试品种的8个产量相关性状与产量的关系及综合性状进行了分析。结果表明,各产量相关性状与产量的关联度从高到低依次为生育期、结实率、千粒重、株高、每穗总粒数、每穗实粒数、有效穗数和穗长;综合性状评析中,与最优组合关联度最高的品种为甬优36,其次为甬优1540和甬优4911。因此,在连作籼粳杂交晚稻高产栽培中,应重点调控生育期、结实率和千粒重;与对照品种甬优1540相比,初步筛选出甬优36和甬优4911两个优质高产品种。

Abstract:

To investigate the effects of different agronomic traits on yield and to preliminarily screen excellent continuous cropping indica-japonica hybrid late rice varieties suitable for planting,the grey relational analysis was applied to analyze the relationships within 8 yield-related traits and yield,as well as the comprehensive traits of 16 tested varieties. The results showed that the relational degrees between yield-related traits and yield in descending order were:growth duration,seed setting rate,1 000-grain weight,plant height,total grains per panicle,filled grains per panicle,effective panicles,and panicle length. In the comprehensive trait evaluation,the variety with the highest relational degree to the optimal combination was Yongyou 36,followed by Yongyou 1540 and Yongyou 4911. Therefore,in high-yield cultivation of continuous cropping indica-japonica hybrid late rice,emphasis should be placed on regulating growth duration,seed setting rate,and 1 000-grain weight. Compared with the control variety Yongyou 1540,2 high-quality and high-yield varieties,Yongyou 36 and Yongyou 4911,were preliminarily screened.

Key words: continuous cropping indica-japonica hybrid late rice, yield, comprehensive traits, grey relational analysis
