摘要
杂种优势现象在林木育种中广泛存在。文中简述了杂种优势形成的3个假说;并通过对林木形态学、生理学和生物化学,分子标记及遗传图谱,基因表达和使用技术的评述,总结出林木杂种优势研究的特点,提出一个研究方法;最后对杂种优势研究的发展方向进行了展望。
Heterosis is a well known genetic phenomenon in the field of wood breeding.This paper briefly introduced three hypotheses on the formation of heterosis,and summarized ten characters of hereroisis in wood based on the reviews of morphology,physiology,biochemistry,molecular marker,genetic map,and gene expression technology.A research method was then produced.Heterosis research orientations were prospected.
