9份具源511S背景的早稻两用不育系主要农艺、品质性状和异交特性研究OACSTPCD
Researches on Main Agronomic,Quality and Outcrossing Characteristics of Nine Early Rice Male Sterile Lines Improved Based on Yuan 511S
为探明以源 511S为背景改良的 9 个水稻两用核不育系的潜在应用价值,调查了改良不育系的主要农艺性状、异交特性、稻瘟病抗性和外观品质性状.结果表明,改良不育系的株型紧凑度、分蘖能力、每穗颖花数、上 3 叶长度和宽度等植株形态性状基本保持了源 511S的特征,部分株系在某些性状上有所改良.9 个水稻两用核不育系作早稻种植的播始历期分别为83～92 d,其中8 个较源511S短0～6 d;改良不育系在开颖历期、颖尖距和开颖角度等性状上变异方向各异,…查看全部>>
To explore the potential application value of early rice dual-purpose male sterile lines improved based on Yuan 511S,the main agronomic traits,outcrossing characteristics,blast resistance and appearance quality traits of the nine im-proved male sterile lines were investigated.The results showed that the plant morphological characters such as plant type compactness,tillering ability,spikelet number per panicle,upper clover length and width of improved male st…查看全部>>
