摘要: 以菊花‘雨花落英’ב奥运含笑’F1群体为材料,调查了2008—2009两个年度开花持续期的分离表现,并基于菊花SRAP遗传图对其进行QTL定位分析。基于单年数据,运用Win QTL Cartographer v2.5软件及复合区间作图法在2008年共检测到3个控制开花持续期的加性QTL,主要分布在秋菊‘雨花落英’遗传图的Y20和Y42连锁群以及夏菊‘奥运含笑’遗传图的A14连锁群上,LOD值介于2.65 ~ 3.44之间,单个QTL对开花持续期表型变异的贡献率为6.54% ~ 11.58%,而在2009年未检测到QTL的存在。运用QTLNetwork v2.2软件对2008和2009两年的表型数据进行联合分析,共检测到两对上位性QTL,在贡献率和效应值上与加性QTL相当,同时上位性QTL与环境之间具有互作效应。

Abstract: In this study,flowering duration stage of chrysanthemum were evaluated in 2008 and 2009,and QTL analysis was undertaken for this trait based on the two-year phenotypic data in 142 F1 mapping population derived from a cross between chrysanthemum cultivars of‘Yuhualuoying’and ‘Aoyunhanxiao’and their SRAP-based genetic linkage maps presently published. The QTL analysis based on the single-year data of 2008 and 2009 with Win QTL Cartographer v2.5 and composite interval mapping method indicated that 3 additive QTL were detected in 2008 but none in 2009. The three additive QTL scattered on linkage group Y20 and A42 of‘Yuhualuoying’map and A14 of‘Aoyunhanxiao’map,with a LOD value of 2.65–3.44 and contribution ratio for phenotypic variation ranging from 6.54% to 11.58% for each QTL. The QTL joint analysis based on the two-year phenotypic data of 2008 and 2009 with QTLNetwork v2.2 suggested that 2 additive-additive epsitatic QTL were mapped,with the similar contribution ratio and effect value to additive QTL detected by Win QTL Cartographer v2.5. In addition,there was interaction between the 2 epistatic QTL and environment.
