为了提高我国黄瓜育种的效率，我们对黄瓜果实和花相关性状进行了QTL定位。本研究在温室条件下，对番茄的侧枝分支数（LBN）、侧枝分支总长度（LBTL）、主茎长（MSL）、节间长（TNL）、主茎粗（MSD）和叶柄长（PL）6个株型性状进行了QTL定位。共检测到14个QTL（LBN，3个; LBTL，2个; MSL，3个; INL，2个; MSD，2个; PL，2个），单个QTL的加性遗传率为1.6%~ 29.5%。在LBN、LBTL、MSL和INL 4个性状上共检测到5个QTL，它们与LBN、LBTL、MSL和INL之间存在显著差异（P <0.05）。
To improve the efficiency of breeding Cucumber ill China, we previously mapped QTL for most fruit- and flower-related traits of this species. Here, we mapped QTLs for six plant architecture traits including lateral branch number (LBN), lateral branch total length (LBTL), main-stern length (MSL), internode length (TNL), main-stem diameter (MSD), and petiole length (PL) were detected in greenhouse environments. In total, 14 QTLs were identified for the six traits (LBN, 3; LBTL, 2; MSL, 3; INL, 2; MSD, 2; and PL, 2) with additive heritability of individual QTL, ranging from 1.6% to 29.5%. Five QTLs for four traits (LBN, LBTL, MSL, and INL) were observed to have significant (P
