摘要
利用加工番茄TD-13和TD-41杂交的185个F2群体,分析与早熟性相关的各生育期性状,并对相关性状进行QTL分析。结果表明:成熟期与始花期、始花节位、结果期、开花至成熟天数呈极显著正相关,与早期结果数,平均单果重相关性不显著。利用复合区间作图法检测到与加工番茄早熟性状相关的12个QTLs。控制始花期和始花节位的QTLs分别检测到3个,控制成熟期和平均单果重的QTLs分别检测到2个,控制开花至成熟天数和早期结果数的QTL分别检测到1个。
185 F2 segregating population which were derived from a cross between TD-13 and TD-41 were used to analyze the correlation of earliness traits between growth periods. And QTLs detection of these traits were employed in this population. The results showed that the days of maturity were positively correlated with the days of first flowering, first flowering node, fruiting period, the days from flowering to maturity, but no correlation with fruite number, average weight of each flute. A total of 12 QTLs were detected by composite interval mapping,including 3 QTLs for the days of first flowering and first flowering node;2 QTLs for maturity and average weight of each fruite;1 QTL for flowering and the days from flowering to maturity.
