| Abstract: | Developed by way of molecular marker-assisted selection,H22A is a new indica-type CMS line with medium amylose content (AC) in rice.In its breeding,firstly,a cross was made between Zhenshan 97B,a high combining ability maintainer line with high AC,and Gui 9B,a fine grain quality maintainer line with intermediate AC.Then,some elite plants in the F4 generation were selected from those lines with fine grain quality (no or less chalkiness) to testcross with Jin 23A.In subsequent successive backcrossing,the mole... |
