Increase of crop production is the primary goal of crop breeding. Rice grain shape is a quantitative trait that is directly related to yield traits and has a close relationship with quality traits. The evaluation of grain shape is mainly grain length, grain width, grain thickness, length/width, and length/thickness. In recent years, the quantitative genetic research on rice grain shape has made a significant progress and a number of important genes associated with rice grain shape have been cloned. This paper reviews the classic genetic analysis on rice grain traits, QTL mapping, grain shape gene cloning and functional analysis, and their application in rice breeding for super high yield.
提高作物产量是作物育种的主要目标。水稻粒形是一个数量性状，直接与产量性状相关，且与品质性状密切相关。粒形评价主要包括粒长、粒宽、粒厚、长宽比和长厚比。近年来，水稻粒形的数量遗传研究取得了显著进展，多个与水稻粒形相关的重要基因已被克隆。本文综述了水稻粒形性状的经典遗传分析、QTL定位、粒形基因克隆与功能分析及其在水稻超高产育种中的应用。
