前言 本试验以直立型和匍匐型品种为材料,经有性杂交,对其后代的生长习性、叶形、茎色素、开花习性、主茎花序等五个性状的显隐性规律、分离规律进行了统计分析,为亲本选配和杂种后代的选择提供理论依据。 材料和方法 一、供试材料 本试验所用的材料是我国栽培种的四大类型:新成早为珍珠豆型,花39为普通型,金堂深窝为龙生型,花28、花37为其他类型。1980年夏季进行杂交,81、82年田间种植,按计划要求的项目进行观察记载。
In this experiment, the vertical and creeping varieties were used as materials, and the sexual habits of their offspring were tested by the sexual intercourse. The recessive regularities and separation rules of their traits such as growth habit, leaf shape, stem pigment, flowering habits and main stem inflorescence The statistical analysis provides the theoretical basis for the selection of parents and hybrid descendants. Materials and methods First, the test material The materials used in this experiment are four types of cultivars in our country: New as early as pearl bean type, flower 39 for the ordinary type, Jintang deep nest for the dragon-type, flower 28, flower 37 Other types. 1980 summer hybrids, 81,82 years of field planting, according to the project requirements of the project records were observed.
