【摘要】 通过对墨宝冬瓜和7个冬瓜高代自交系配制的9个杂交组合的子房长、子房横径、成熟瓜长和成熟瓜横径4个农艺性状进行相关性分析,以期揭示冬瓜子房与成熟果实的遗传相关性,为根据子房大小预测成熟果实大小提供依据。结果表明,子房长与成熟瓜长呈正相关且达极显著水平,与成熟瓜横径呈显著正相关。该研究为冬瓜育种和生产提供理论参考。更多还原

【Abstract】 In this study, four agronomic traits,including ovary length, ovary width, mature fruit length and mature fruit width were investigated in the experimental field among Mobao Donggua and 9 hybrids made between 7 inbred lines.Thereafter, the correlation analysis and path analysis were performed to reveal the relation between ovary and mature fruit in wax gourd.The results indicated a extremely significant positive correlation between ovary length and mature fruit length, and a significant positive correlation between ovary and mature fruit width.It was found that mature fruit width had a positive correlation with mature fruit length.This study provided theoretical reference for the breeding and production of wax gourd.更多还原
