【摘要】 为探明甘薯维生素C和胡萝卜素含量的基因型与环境效应 ,精选 11个有代表性的甘薯品种 (系 ) ,分别在 5个产地进行多品种多试点有重复的品质稳定性研究。结果表明 ,在随机效应中 ,甘薯维生素C的试点效应最为明显 ,而胡萝卜素则以基因型与试点互作效应最为明显。这表明需针对甘薯不同品质特点筛选和确定不同品种所适宜种植的地区 ,或不同地区所适宜种植的品种 ,以实现优质品种优质生产目的。更多还原

【Abstract】 The purpose of this study was to investigate the effects of genotypes and production locations on the contents of vitamin C and carotene in sweetpotato. Eleven superior genotypes were grown at five production locations with three replicated field designs. The analysis of variance indicated that produetion locations significantly effected the vitamin C content, but there was highly significant genotype by environment interaction effect for the carotene content. Therefore, the planning of sweetpotato production in areas favorable for increase in the vitamin C and carotene contents is recommended. Selection of cultivars with stable performance in vitamin C and carotene content is also suggested.更多还原
