大豆（Glycine max [L.]）生育期长短影响籽粒产量。[Merr])，而对生育期的遗传控制可能有助于提高产量。为了检测控制繁殖周期的遗传因素，以日本地方品种“一本-山吾”和日本栽培品种“福丰”为材料，利用开花至成熟期（DFM）与播种至开花期（DSF）的差异，杂交获得了重组自交系（RILs）群体。在RIL人群中，在3年的所有田间试验中，DFM与DSF相关性较差（r = - 0.16至0.34）。在染色体（Chr-） 10和11上鉴定了两个DFM的稳定qtl，在染色体（Chr-） 10和-16上鉴定了两个DSF的稳定qtl。3个试验均受chrr -11上生育期QTL（命名为qDfm1，花期至成熟期数量性状位点1）的影响，其中福丰等位基因的促进期较长，qDfm1是造成福丰与一本-山果DFM差异的主要原因。qDfm1主要影响生殖期，因此有可能在对营养期影响不大的情况下改变生育期。
The length of the reproductive period affects the grain yield of soybean (Glycine max [L.] Merr), and genetic control of the period might contribute to yield improvement. To detect genetic factor(s) controlling the reproductive period, a population of recombinant inbred lines (RILs) was developed from a cross between Japanese landrace ‘Ippon-Sangoh’ and, Japanese cultivar ‘Fukuyutaka’ which differ in their duration from flowering to maturation (DFM) relative to the difference in the duration from sowing to flowering (DSF). In the RIL population, the DFM correlated poorly (r = −0.16 to 0.34) with the DSF in all field trials over 3 years. Two stable QTLs for the DFM on chromosomes (Chr-) 10 and 11 as well as two stable QTLs for the DSF on Chr-10 and -16 were identified. The QTL on Chr-11 for the reproductive period (designated as qDfm1; quantitative trait locus for duration from flowering to maturation 1) affected all three trials, and the difference in the DFM between the Fukuyutaka and Ippon-Sangoh was mainly accounted for qDfm1, in which the Fukuyutaka allele promoted a longer period. qDfm1 affected predominantly the reproductive period, and thus it might be possible to alter the period with little influence on the vegetative period.
