我国北方小豆地方品种资源研究 Ⅷ .不同地区小豆地方品种群体农艺性状的表现

笔者对我国北方吉林、辽宁、北京、河北、天津及江苏小豆地方种质资源群体的农艺性状在北京地区所表现的遗传参数进行了研究。研究表明:不同地区小豆地方品种群体农艺性状在北京地区的平均表现及遗传变异度是不同的,系统选育新品种时应根据小豆地方品种农艺性状的特点及其遗传潜力分地区进行;在北京地区进行早熟、高产新品种系统选育时,以吉林、辽宁、北京的材料较好;若在北京地区进行大粒品种系统选育,以河北、北京的材料较好。

Study on Adzuki Bean Variety Sources in North China Ⅷ. Agronomic Performance of Adzuki Bean Local Varietal Groups from Different Areas

The genetic parameters exhibited in each of adzuki bean local varietal groups from Jilin, Liaonin, Hebei, Beijing, Tianjin and Jiangsu were studied in Beijing area. The average value of genetic parameters and the genetic variation of agronomic characters recorded from local varietal groups of different areas, are varied in Beijing area. According to this study, it is better to make use of genetic resources from Jilin, Liaonin and Beijing to breed for precocious and high yield new varieties by systematic breeding method in Beijing area; and for new varieties with large seed in Beijing area, it is better to utilize genetic resources from Hebei and Beijing areas.
