为了筛选出理想的穗形、粒形近等基因系,对以粳稻品种‘日本晴’为背景亲本、以大穗品系‘R1126’和大粒品系‘TDX’为供体亲本构建的大穗、大粒株系进行了评价。结果表明:P01、P05、P09、P19和P20株系每穗粒数显著多于日本晴,而其他农艺性状与日本晴基本相当;G08和G09的粒重、粒长显著大于日本晴,而株高、穗长、每穗总粒数、结实率和单株粒重等性状与日本晴相当。这些株系是基于日本晴背景的理想大穗、大粒近等基因系,为后续的深入研究提供了基础材料。

A set of rice lines with large - panicle or large - grain were developed,which have the background parent of ja-ponica rice variety Nipponbare, and the large - panicle line R1126 and the large - grain line TDX as the donor. In order to screen the ideal near - isogenic lines with different panicle size or grain size,thirty - three lines were evaluated. The results showed that the number of grains per panicle of P01 ,P0 5 ,P09 ,P19 and P20 lines were significantly higher than that of Nipponbare, while other agronomic characters were similar to those of Nipponbare. Grain weight and grain length o...
