西瓜种质资源主要园艺学性状的评价

通过对不同起源分类的西瓜种质资源的大田试种，并对其生育期、果实性状和产量结构的测定和部分Ｆ１代性状的遗传分析，获得了部分优良地方品种资源的主要生物学和遗传学特性的资料，特别是通过对西瓜种质资源的室内苗期抗性人工接种鉴定和温室成株期的强化筛选，获得了一批农艺性状较优良的抗性材料，为下一步的西瓜品种改良和育种工作提供了丰富的第一手资料。

AN EVALUATION ON MAIN HORTICULTURAL PROPERTIES OF WATERMELON GERMPLASM

The developing period,the fruit properties and the output structure of the different germplasms and F1 hybrids of watermelon have been tested in the field. Especially with the artificial resistant identification and selection of indoor seedling and at mature stage in greenhouse. The results showed that some local varieties which biological and genetic properties had been observed were good quality and resistant to watermelon fusarium wilt,the varieties from America were late ripen,large fruit,good storage and high resistance,but they were no good quality. All results were useful for breeding of new watermelon varieties.
