China is a plum, apricot germplasm centers of genetic diversity, has the most extensive plum, apricot germplasm. Abroad by Lee, apricot interspecific hybridization have been bred a series of excellent varieties (apricot and plum), the quality of these varieties are more than at home and abroad plum, apricot varieties, apricot and plum varieties, but due to the international protection of intellectual property rights of a large number of commercial cultivation by the restrictions, set off by domestic apricot, plum cultivars hybridized with apricot and plum and apricot, plum creation of new varieties of hybrid boom. Lee, apricot species prevalence of hybrid incompatibility phenomenon, in which the varieties of self-incompatibility is one of the reasons lead to hybrid incompatibility. In addition, Lee, apricot production since the incompatibility presence, must be artificial pollination or configuration pollinated varieties in order to ensure stable and high, also need to determine the self-incompatibility genotypes. The 38 Lee, 18 apricot landraces and seven apricot plum cultivars used as experimental materials, the 63 Li Yake fruit trees self-incompatibility genotypes were isolated and identified 15 new pistil self-incompatibility gene and three new pollen self-incompatibility and genes, on this basis, according to the S-genotypes of apricot, plum, apricot and plum varieties, flowering, fruit, fruit size, filter out 15 kinds of interspecific hybridization good parents and 66 possible crosses, new varieties of hybrid between a plum and apricot species created to provide an important theoretical basis. (1) identified 63 plum, apricot, apricot and plum varieties S genotype. 'Taste' Sh / Se, the 'Weihou' Sh / Se 'flavor Rose' S genotype are SH / Se; 'dinosaur eggs', 'taste Emperor', 'flavor Queen' S genotypes are 'S1/Sb; Crystal' Honey Lee ',' Lee ',' ominous Lee 'S genotype are SC / Se;' hollow Lee, Batang Lee 'S genotype are S10/S11;' Sui edge red plum ',' Early Huang Li 'S genotype are S10/Sg;' Li Zaimei ',' wheat yellow 'S genotype are S10/S22;' nuclear ',' from The nuclear 'S genotype are S11/Se. S-genotypes of other varieties as follows: 'Xinjiang' S17/S8 'cinnabar Lee' S11/S8 ',' flat-topped incense 'Sk / Se' barley 'S10/S8,' qingzhou Lee 'S41 / sc, 'Lian Ping spent three Lee' S10/S6, 'Early Lee' S10/S15, S17/S10 'hengdaohezi Scarlet Lee', 'Apple Lee' S15/S16, 'Green T. chicken Lee' S17/S11 'Li Furong' Si / Se 'precocious Lee' S9/S18, the 'Sands Li' S18/S10, 'rhubarb Lee's S10/Sg,,' Qiu Li 'Sb / SG,' Kang Shi Lee 'S10/Se, , 'Fenghua Lee' S7/Sb,, 'the melon Lee' S32/S11, 'gray Lie' S17/S32, 'the precocious red plum anvil' S18/S9 'peacock eggs seedling' S10/S8 'nameless Lee' S17/S8, 'Guangdong Hearts Lee' S10/S14, the 'spiced Lee' SK / SE 'leaves in the possession of' S3/S35, 'Naiman late-maturing' S22/S11 'Badou apricot' S11/S26 'friendship Argent 'S12a/S26,' 克孜克西米 West 'S14a/S9,' earthy white 'S22/S4a,' Zhejiang apricot 'S17/S37,' Black Leaf apricot 'S8/S27' of Jinxi large Apricot ' the S16/S22, '9803 'S12/S3,' Kim Kyu 'the S22/S17' Silver Hong White 'S23/S36,' Longken 5 'S39/S8' Guanye face 4 'S24/S38' Lanzhou apricot 'S11/S22a' Shajinba red 'S16/S22b,' taste Xin 'S2/Se,' white flowers Lee 'S10/Sx,' late-maturing Huang Li Anvil 'S8/Sx,' May Lee 'S10 / Sx 'Guangdong Red Lee' S23/Sx, 'County purse apricot' S40/Sx. (2) Identification of the 15 new S-RNase gene and three new SFB gene. 'Qingzhou Li', 'Guangdong-Hong Lee', 'silver' friendship, 'silver fragrant white', 'shakin red', 'Lanzhou big apricot', 'Longken' 'Guanye face No. 4' 15 varieties 'leaves in the possession of' 'counties purse', '克孜克西米 West', 'melon Lee', 'Zhejiang apricot', 'earthy white' isolated S41, S23, S12a, S36, S22b, S22a, S39, S38, S35, S40, S14a, S32, S37, S4a, S23-RNase 15 new S-RNase gene: 'melon Lee', 'Zhejiang apricot', 'earthy white' varieties were isolated and identified the new pollen SFB gene: SFB32, SFB37, to SFB22 that,. (3) filter out 15 excellent hybrid parents and 66 viable hybrid combinations. According to the fruit quality, fruit size filter out 'Sha Jin Hongxing' 'Xin flavor', 'honey Li' 'style roses', 'dinosaur eggs', 'Wei Hou', 'taste', 'Fenghua Li' 'Kangshi' the 'Batang Lee', 'Queen of flavor', 'taste Emperor', '克孜克西米 West', 'Lanzhou big apricot', 'flat-topped incense' 15 fine varieties, combined with S-genotype and flowering, and eventually filter out 66 viable interspecific crosses, Li Yake interspecific hybrid varieties created to provide theoretical guidance.
