Principles and practices of the photo-thermal adaptability improvement in soybean

摘要

cqvip:As a short-day(SD)and thermophilic plant,soybean(Glycine max(L.)Merr.)is sensitive to photo-thermal conditions.This characteristic severely limits the cultivation range of a given soybean cultivar and affects the performances of agronomic traits such as yield,plant architectures,and seed quality.Therefore,understanding the mechanism of photo-thermal sensitivity will provide a theoretical basis for soybean improvement.In this review,we introduce the advances in physiological,genetic,and molecular researches in photoperiodism of soybean,and progress in the improvement of the photo-thermal adaptability.We also summarize the photo-thermal conditions and characteristics of widely-planted soybean cultivars of major production regions in China.Furthermore,we proposed a novel concept of‘ecotyping’and the strategies for widely-adapted soybean cultivar breeding.This review provides an important guide for improving the adaptability of soybean.
