我所自1959年起开始进行柑桔人工杂交育种的研究工作。第一批杂交选36个柑桔品种为亲本,组成157个种间、品种间组合。现保留50个组合、540个实生单株.二十五年来,经过系统地考种,鉴定,从中筛选出性状优良的单株3个。同时总结了柑桔杂种一代胚型及某些性状的遗传特点。为柑桔杂交育种提供了依据。 优良单株的性状 由杂交种子播种的540个实生后代中,出现了各种类型的变异。除了与母本一致的珠心系个体外,也发现超越母本的珠心系变异。但多数后代都明显地表现出双亲遗传的 Since 1959, we have started research on artificial breeding of citrus. The first batch of 36 selected citrus varieties as parents, composed of 157 species, the combination of varieties. Now there are 50 combinations and 540 live single plants, and in the past 25 years, 3 plants with excellent traits have been screened out and screened systematically. At the same time, the genetic characteristics of the embryo type and some traits of citrus hybrids were summarized. It provided the basis for cross breeding of citrus. Traits of Good Individuals Of the 540 real offspring sown by hybrid seeds, various types of variation have occurred. In addition to consistent with the mother of the pearl heart individuals, but also found beyond the mother of the pearl heart variation. However, most of the offspring clearly showed parental inheritance
