对２１个杂交组合、１０４９株一代植株果形调查测定表明，柑桔一代杂种果形呈连续性变异。杂种果形指数与亲中值及母本果形指数均呈极显著正相关，果形呈趋中或趋扁变异。圆形果和椭圆形杂交后，果形指数略低于亲中值；扁圆形果与椭圆形果或圆形果杂交，果形为趋中变异，果形传递可达１００％。
The results of fruit shape survey on 1049 first generation hybrids of 21 hybrid combinations showed that the fruit shape of the first generation of citrus hybrids showed continuous variation. The hybrid fruit shape index had a significant positive correlation with the pro-median value and the female fruit shape index, and the fruit shape tended to change or flatten. The fruit shape index is slightly lower than the pro-medium value after the cross between the round fruit and the oval shape. The oblate fruit is crossed with the oval fruit or the round fruit. The shape of the fruit is in-going variation and the fruit shape can reach 100%.
