chinois. 以早熟桃品种‘筑波84’ב早油118’杂交组合为试材,分析了F1代果实主要性状的遗传倾向.结果表明：F1代果实形状中,卵圆形对椭圆和圆形占遗传优势;F1代果实成熟期集中分布在80-90 d和100-110 d 2个区域,而分布在90-100 d的杂种单株较少,只占9.6%;F1代平均果重与父母本和亲中值相比,呈现偏小趋势;在F1代群体中,大部分桃果实风味趋向于甜或酸甜,其中甜风味占40.35%,遗传性强;F1代果肉颜色、有无绒毛及核的粘离等均由一对等位基因控制,试验结果均符合孟德尔遗传规律;果实重量与果实生育期呈极显著正相关,可溶性固形物和风味呈极显著正相关.[著者文摘]

The inheritance trend of main characters was studied in early peach variety F1 progenies of ＇Tsukuba-84＇×＇ZaoYou118＇.The results showed that heritability of oval was higher than round and elliptic in the fruit shape.The maturity date distributed in 80 to 90 days and 100 to 110 days,and only 9.6 % of the plants distributed in 90 to 100 days.The fruit weight showed a smaller tendency and it was lower than male,female and mid-parent in F1 progenies.The F1 progenies exhibited the tendency of sweet flavor or sour-sweet flavor,and sweet flavor showed stronger than the other characters,occupied of 40.35 %.Fruit color,hair and stone adherence to flesh in F1 progenies were controlled by a pair of independent alleles each.The results were consistent with Mendelian inheritance of genetic.There were significant positive correlations between fruit weight and the maturity date,and between soluble solid content and flesh flavor.
