小麦早熟性是与高产稳产密切相关的重要经济性状之一。随着耕作制度的改革和提高复种指数,以及防御生育后期多种自然灾害,小麦早熟性的遗传越来越受到国内外小麦遗传育种工作者的重视。国内主要对抽穗期的遗传进行丁大量研究,多数研究者获得了早抽穗倾显性和部分显性遗传的一致趋势;国外多偏重于小麦春化和光照反应遗传规律的研究和利用非 Wheat precocity is one of the important economic traits closely related to high and stable yield. With the reform of cropping system and improvement of multiple cropping index and prevention of multiple natural disasters during later growth period, the inheritance of wheat prematurity has been paid more and more attention by domestic and foreign wheat genetic breeding workers. Most domestic researches on the inheritance of heading date have been carried out in large numbers, and most of the researchers have obtained the consistent trend of tillering dominant and partial dominant inheritance of heading date. Many foreign researches focus on the genetic law of wheat vernalization and light response
