Abstract
A group of tropical and subtropical breeding materials were crossed with inbred lines 5003,Mo17(Ht) and Dan 340 in Shenyang region,then backcrossed, The results indicated that: Not all the tropieas and subtropical germplasm can improve loging ratio of inbred lines. The tropical and subtropical germplasm of different sources differed from effect to improve lodging ratio of inbred lines. In the same combination, the tropical kin accounted for different proportion, the improved effect of lodging ratio was different. The ideutical tropical and subtropical germplasm was improved with different effect to the different inbred line, subtropical germplasm can improve Reid loging ratio, tropieas can improve Lvdahonggu loging ratio.
