【摘要】 作为一种粮食、蔬菜、饲料、绿肥兼用的食用豆类,蚕豆在人类健康、土壤改良等方面发挥了重要作用。高密度遗传图谱的构建是蚕豆基因组研究的基础和主要手段,至今共构建了24张蚕豆遗传图谱,最为饱和的图谱覆盖长度为1 439 cM,平均遗传距离为0.8 cM。同时基于图谱开展了产量相关性状、品质相关性状以及抗性相关性状的QTL定位,有效地促进了蚕豆的遗传与基因研究。更多还原

【Abstract】 As a kind of edible legumes which can be used as food, vegetables feed and green manure, Vicia faba L. plays a crucial role in human health and soil improvement. The construction of high-density genetic linkage map is the basis and main method for genome research in V. faba L.. 24 genetic maps have been constructed so far, in which the most saturated map spanned 1 439 cM with an average genetic distance of 0.8 cM. Quantitative trait locus(QTL) mapping on yield-related traits, quality-related traits, and resistance-related traits had been carried out, which effectively promoted inheritance and gene research in V. faba L..更多还原
