童期是果树从种子播种发芽到实生苗第一次开花结果的年限。以童期的长短作为衡量早实性强弱的标准,早实性强的其童期短,反之则童期长。果树杂种实生苗的童期一般较长,如何使杂种实生苗缩短童期,提早结果,是加速育种进程的重要方面。关于果树早实性问题前人已有过一些报道。有关枇杷的早实性遗传及其相关问题的研究,在国内外至今尚未见到报道。从枇杷的遗传性上来探索早实性的遗传规律,是加速育种进程,提高育种效能的重要组成部分。本试验的目的是研究枇杷的品种间杂种
Childhood is the fruit tree from seed sowing to seedlings the first time the result of flowering. The length of childhood as a measure of the strength of early solidity, strong early childhood short, otherwise the long childhood. Fruit hybrid seedlings of childhood generally longer, how to make hybrid seedlings shorten the period of childhood, early results, is an important aspect of accelerated breeding process. There have been some reports on the early fruit of fruit trees. The research on the early solid sex and related problems of loquat has not been reported at home and abroad so far. From the heredity of loquat to explore the genetic law of early solidity is to speed up the breeding process and improve the breeding efficiency of an important part. The purpose of this experiment is to study the inter-species hybrids of loquat
