Abstract
Through cross experiment between Northwest group and other cultivar groups of Paeonia suffruticosa, and taking the single flower seeds as the index of affinity, the crossbreeding among Paeonia suffruticosa populations was studied. The results showed that when taking Northwest cultivar group as female parent, and crossbreed with Zhongyuan cultivar group and Japanese cultivar group respectively, no incompatibility was found, and higher average seed setting rate, 14.6 grain / flower and 9.8 grain / flower was obtained respectively. When Northwest cultivar group crossbreed with Europe and America group, there was a certain fecundity, but the seed setting rate was very low, which was 0.4 flower/seed. And there was incompatibility between Northwest cultivar group and Ito hybrid group. This study provided reference bases for the crossbreeding between Northwest group and other cultivar groups.
