| Abstract: | SD9238 is a new genetically controlled semi-dwarf selection which was found in 25-10×Mayfire: progeny. The cross was made in spring of 1992 in Zhengzhou Fruit Research Institute,CAAS. It's characterized by smaller canopy,less number of new shoots and shorter internodes than those of standard type. The fruit of SD9238 mature in the beginning of June. Its round, full-covered with red blush fruit weighs around 120 g. The flesh is white and melting. The fruiting index is a little low. The genetic analysis shows that the semi-dwarf trait is controlled by a single dominant gene. It's an excellent germplasm for peach breeding and has a cheerful prospect. |
