摘要: Legume seeds have the potential to provide a significant portion of essential micronutrients human diet. To identify genetic basis for seed nutrient density, quantitative trait locus (QTL) analysis was conducted with Miyakojima MG-20 × Gifu B-129 recombinant inbred population from model legume Lotus japonicus. This grown under greenhouse conditions in 2006 and 2007. Phenotypic data were collected calcium (Ca), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), phosphorus (P), sulfur (S), zinc (Zn) concentrations content. Data physical traits (average mass seed–pod allocation values) also collected. Based on these phenotypic data, QTL analyses identified 103 linked 55 different molecular markers. Transgressive segregation, within this both traits, suggests new allelic combinations are available agronomic improvement. Q...
