所检测到的耐冷性QTL的增效等位基因多数来自吉冷1号，基因作用的方式主要为部分显性、显性和超显性。
Most of dete cted QTLs allele were come from cold-tolerant parent Jileng 1. The gene action was partial dominance, dominance and over dominance primarily.
对每个QTL（定量特征点位分析） ，均检测到加性和显性效应，但相对大小有不同，各QTL以部分显性、显性和超显性为主要遗传方式；
For each QTL, both additive effect and dominant effect were detected. Most QTLs had the genetic effect of partial dominance, dominance or overdominance.
