Germplasm resources is the new breeding indispensable material foundation , and also the genetics , taxonomy, biology , and other important materials for fundamental research . In this paper, a method of combining route survey and individual surveys on the status of the semi-arid regions wild apricot germplasm resources research , and further determined Biochemical genetic characteristics of excellent type and variant type , the results show that : the semi-arid region mountain apricot is rich in resources , the degree of pistil development , fruit weight , the nucleation rate long , twigs , nuclear weight , peel thickness , kernel weight , kernel rate , of nine Union shape index quantitative trait variation greater , as the distinction between mountain main traits of apricot germplasm resources ; groups within a considerable sense of individual variation is mainly manifested in the tree , flowers , leaves, fruit , nuclear , benevolence , stress resistance in seven areas , the survey found that 20 kinds of variation type , epitomized in the 50 representative strains of these types of mutation types , including umbrella crown apricot, naturally happy wild apricot , pink flower wild apricot , large floral apricot, late flowering wild apricot petals fold wild apricot , double pistil wild apricot , plena wild apricot pistil development completely wild apricot peel wild apricot the heart shaped Ye Shanxing , erythema point , sweet meat sweet benevolence wild apricot , bitter meat sweet benevolence wild apricot , double Ren wild apricot , large nuclear wild apricot , nuclear wild apricot , a small oblate nuclear wild apricot , small round drum nuclear apricot, the Youth Pre-employment Training nuclear apricot, antifreeze wild apricot ; correlation analysis showed yield the largest tree factor is the crown width ; combination of the characteristics of the relevant research and wild apricot , the the flourishing time wild apricot results determine the semi-arid areas 100 / m to the the crown check indicators for high yield wild apricot , flowering Prunus sibirica flowering than ordinary six days later for the late-flowering the wild apricot complex selection criteria , 44 two-year investigation of high yield eight late flowering excellent tree ; application wild apricot leaf POD isozyme and seed soluble protein consecutive double vertical polyacrylamide gel electrophoresis (PAGE) technology, research -based high yield, late flowering , frost primaries excellent strains wild apricot groups genetic characteristics , cluster analysis of the test sample is divided into 14 classes and 16 classes , two biochemical markers consistent classification results biometric consistent with the morphological characteristics that both as the wild apricot genetic classification biochemical indicators .
