Identification of SRAP markers linked to peach gene with the character of tall normal/brachytic dwarf
摘要
Abstract
Close planting by brachytic dwarf peach is one of the main direction for peach industry.About 123（1-year-old） hybrid individuals derived from the cross of Shouxing Tao peach（Prunus persica var.densa Makino） A20 and peach [P.persica（L.） Batsch] 99-12-34 which was used to identify SRAP markers linked to the character of tall normal/brachytic dwarf for understanding of the dwarfing mechanism.The individuals were divided into two types.About 63 individuals have the character of brachytic dwarf and 60 individuals have the character of tall normal.Altogether,336 pairs of SRAP primers were screened by bulked segregant analysis（BSA）.Finally,a SRAP marker,Me11Em25,which linked to the character of tall normal/brachytic dwarf at a distance of 3.2 cM,was selected.The marker wea used to test in 34 varieties and has the coincidence rate of 88.2%.The results showed the marker could be used for molecular assisted selection（MAS） in peach.关键词
