    摘要:

    以优良鲜食枣品种‘蜂蜜罐’的131个实生后代为试材,对其果实描述型性状和数值型性状进行了观测。结果表明:变异系数最大的3个性状为裂果率、单株产量和可滴定酸含量;变异系数最小的3个性状为含水量、可食率和果实硬度。实生后代中,小于50%的后代在果实颜色、果皮厚度、果肉颜色、果肉汁液量和果实风味与母本表现相同或相似。对果实硬度、可溶性固形物含量、可滴定酸含量等8个性状进行了相关性分析,发现可滴定酸含量与含水量呈极显著正相关,与可溶性糖含量呈极显著负相关;Vc含量与可溶性固形物含量呈极显著负相关。运用灰色关联分析和分值累计法筛选出综合性状优良的种质3个、富含可溶性总糖的种质2个、富含可滴定酸的种质5个及富含Vc的种质5个。

    Abstract:

    The character variation analysis and superior individual selection were accomplished by observation and measurement on the fruit traits of 131 progenies from natural pollination of ‘Fengmiguan’jujube (Ziziphus jujuba Mill.‘Fengmiguan’). The results showed that the variation coefficients of fruit cracking rate, yield per tree and titratable acid content were the largest, while those of water content, edible rate and fruit rigidity were the lowest. Only less than 50% progeny seedlings shared the same or similar phenotype with maternal plant in fruit color, pericarp thickness, flesh color and juicy, fruit flavor and so on. Correlation analyses among 8 characters including fruit rigidity, soluble solid content, titratable acid content etc. showed that titratable acid content had significant positive correlation with water content and had significant negative correlation with soluble sugar content. Vc content had significant negative correlation with soluble solid content. At last, 3 seedlings with excellent comprehensive characters were screened out through grey correlation analysis and synthetical weighted mark method. In addition, 2 seedlings with high soluble sugar content, 5 seedlings with high titratable acids content and 5 seedlings with high Vc content were selected out.
