【目的】探究‘沙田柚’与枸橼杂交后代叶形态学性状的遗传趋向性与相关性。【方法】以单胚、易感溃疡病品种‘沙田柚’为母本,与单胚、抗溃疡病种质枸橼C-05进行杂交,将得到的848株杂种后代作为研究对象,对其叶片形态学性状进行遗传趋向分析与偏相关分析。【结果】F_1代叶尖指数、叶形指数、翼叶宽度性状受母本的影响较大,叶柄长度性状、新叶颜色性状受父本的影响较大,叶尖指数、叶形指数表现为趋小变异,翼叶宽度表现为趋大变异,叶柄长度表现为趋中变异;有翼叶对无翼叶表现为显性,紫色新叶对绿色新叶表现为显性;新叶颜色与翼叶宽度、叶柄长度呈极显著负相关,与叶尖指数呈显著负相关,而与叶形指...

【Objective】The experiment aimed to explore the genetic trend and correlation of the leaf morphological characters of the hybrids between‘Shatian’pumelo and citron C-05【. Methods】848 hybrids were obtained from the cross between the mono-embryonic female parent‘Shatian’pumelo susceptible to citrus canker disease and the mono-embryonic male parent citron C-05 resistant to citrus canker disease. 756 hybrids were chosen for the analysis. The main leaf characters including leaf length and width, petiole wing width, petiole length and leaf tip...
