| Abstract: | The maintainer line 29B is a male-sterility maintainer line of indica rice with great combining ability,aroma and good grain quality.On the preliminary work our lab using 29B bred a new maintainer line 1978B which contain Pi2.Now we used the donor 2048B to pyramid 3 resistance genes Bph14,Bph15,Pi1 into 1971B by anther culture and molecular marks assistant selection.One of the DH lines SF-1 which contain the 4 resistance genes(Bph14,Bph15,Pi1,Pi2) performed well in the tests of leaf blast and brown planthop... |
