在桃树生产上,果实短发育期是一项重要的经济性状。因此,大多数育种者把培育早熟桃作为重要的选育目标。桃果实短发育期遗传方面的研究,已提出了自花和杂交授粉的果实成熟时期的分布状况,后代分布比率,完熟期的遗传率等问题。因为大多数栽培品种的花期是比较集中的,所以早熟、成熟所需的时间、成熟日期和完熟期与温带桃树果实发育期长短差不多 In peach tree production, short fruit development is an important economic trait. As a result, most breeders target the cultivation of precocious peach as an important breeding target. Studies on the genetic aspects of peach fruit short developmental period have proposed the distribution of fruit ripening period, the distribution ratio of offspring and the heritability of maturity stage of self-pollination and hybrid pollination. Because the flowering of most cultivars is relatively concentrated, the time required for maturity, ripening, maturity and maturity is about the same as the developmental period of the temperate peach tree
