摘要
对辣椒的8个自交系13个数量性状进行了聚类分析,应用欧氏距离,采用类平均法在阈值为19.05水平下,将其分为4类。选择距离较大且来源不同类群的品种进行组配,有望获得高优势组合,提高优势育种亲本选择选配的效率。
Eight pepper parental inbred lines were classified into four groups on 19.05 clustering level by the distance calculated on 13 agronomic quantitative characters. The relative inbred lines were clustered into the same group. Crossing parents would come from different clusters.This would get higher heterosis in pepper and can increased breeding effectiveness for breeder.
