以核酸逢機增殖多型性 (RAPD) 遺傳歧異度預測玉米雜種優勢之研究

Abstract

本研究係以20個逢機序列之核酸引子偵測7個玉米自交系間之遺傳歧異度，並將估得的遺傳歧異度與7個自交系進行半互交所得之F1雜交種表現（特殊組合力效應，產量）進行相關分析，期望能了解以核酸逢機增殖多型性預測雜交種表現之可能性。To evaluate the potential of RAPD-based genetic diversity in predicting the performance of hybrids, the genetic diversity among maize inbred lines was dectected with random amplified polymorphism. Modified Roger's Distance (MRD) among seven maize inbred lines was between 0.53 and 0.75 based on 88 bands using 20 primers.
