两种株型水稻品种杂交后代品质性状与农艺性状的研究

Studies on the Qualitative and Agronomical Traits of GenerationHybridized Between Two Kinds of Later Rice Panicle Types

直立穗型与弯曲穗型水稻品种杂交后代外观品质的变异幅度最大,碾磨品质变异幅度最小,其它品质性状变幅居中。某些品质性状与农艺性状指标之间存在相关关系。供试材料中直立穗型穗行常常较弯穗型穗行表现出较低的碾磨品质和外观品质。

To the later generation hybridized between erect and crooked panicle type, the degree of variation of physical quality is biggest, milled quality is least and the others are in the middle. Some kinds of qualitative and agronomical traits are correlative. The erect panicle varieties always have lower milled and physical quality than the crooked panicle type.
