Abstract:
The objective of this study is to explore the probabili ty that molecular marker distance could be usedto predict heterosis .32 accessions including 10 cultivars , from 6 cities and provinces, and their F1 hybrids w erestudied on genetic distance by using SSR markers .The results were as the follow ing :Parents selected within theso rt could be more helpful to increase number of main stem branch and pods per plant than those selected betweenso rt s .In most F1 hy brids with one same parent , ag ronomic trait s and heterosis were not related to geneticdistance .Mid parent heterosis of 100 -seed weight and high parent heterosis of number of main stem branch intotal F1 hy brids appeared highly curvilinear co rrelated to genetic distance respectively .
