Abstract
The lodging indexes of CMS lines of japonica rice(Yixing1A,II-32A and Gang46A),7 restorer lines(Yihui7633,Yihui7008,Yihui1525 and others) and their hybrid progenies were determined.The results showed that significant differences existed between the paternal and maternal parents in their lodging index,especially that of the third internode from the top.These differences had a direct influence on the progeny,the maternal parent having a greater influence.Generally speaking,the progeny had strong lodging resistance if the parents had strong lodge resistance.Interaction between the parents and genotype environment interaction were observed.
