国内外对花生高产育种的选择指标,虽有不少报导,但提法很不一致,对花生育种中的高产选择,至今基本无确切有效的选择指标可循,仍然停留在依靠感官判断的水平上。作者于1977年和1980年以15个主要经济性状进行了花生高产育种选择指标的研究,发现荚果/茎叶比值有着较宽的遗传变异度、较高的遗传力和遗传进度,与小区产量呈显著的相关关系,可以作为花生高产选择的指标。 一、材料及方法 从山东省近几年来选育推广的新品种
Although there are many reports about the selection index of high-yielding peanut breeding at home and abroad, the formulation is very inconsistent. To the selection of high-yielding peanut breeding, there are basically no exact and effective selection indicators to follow, and still depend on the level of sensory judgment . In 1977 and 1980, the author studied the selection index of high-yielding peanut breeding with 15 major economic traits. It was found that the pod / stem-leaf ratio had a wide range of genetic variation, high heritability and genetic progress, Significant correlation can be used as an indicator of high yield of peanut. First, materials and methods From Shandong Province in recent years breeding new varieties
