摘要
以内蒙古扎兰屯地区山杏为试材,通过对其群体性状进行研究,调查树体因子、正态性检验和相关性分析。结果表明:28个山杏数量性状呈正态分布,其中变异系数最大的为嫩枝长,达48.7%;叶柄长、完全花比例、嫩枝粗、叶宽、叶柄粗、核重等变异系数均超过20%。核重、仁重与嫩枝粗、节间长度、叶长、叶宽、叶柄长、叶柄粗、核长、核宽、仁长、仁宽和果重显著相关;出核率与果厚显著相关,出仁率与核宽、核厚、仁厚和核重显著相关。综合变异性分析和相关性分析,确定嫩枝长、嫩枝粗、节间长度、叶形指数、果重、果厚作为当地山杏间接选种的主要数量性状指标。
Taking Armeniaca sibirica in Zhalantun county of Inner Mongolia as material, the distribution characristics variabilities and correlation with character of Armeniaca sibirica were analyzed. The results showed that Armeniaca sibirica twigs, flowers,leaves, fruits and kernels, 28 quantitative traits were normally distributed. Length of twig had the biggest coefficient variation which was 48. 7 % ; the coefficient variations of petiole length, the proportion of complete flower, twig thickness, leaf width, petiole thickness, kernel weight were over 20 %. Kernel weight and almond weight were significantly associated with twigs thickness,internodes length,leaf length,leaf width, petiole length,petiole coarse, kernel length, kernel width and weight kernel rate was significantly associated with fruit thickness, almond rate was significantly associated with kernel width and thickness. Combining characters variation analysis and related analysis, the main quantitative character of local high-yield Armeniaca sibirica indirect selection index were the twig length, twigs thickness, length of internodes, fruit weight and flesh thickness. Keywords. Armeniaca sibirica ; population traits; quantitative traits
