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。 To identify the genotype and environmental effects of vitamin C and carotenoid content in sweet potato, eleven representative sweet potato varieties (lines) were selected and tested for reproducibility and quality at five locales. The results showed that in the random effects, the most obvious experimental effect of vitamin C in sweet potato, while the carotene genotype and pilot interaction effect most obvious. This indicates that different quality characteristics of sweet potato should be screened and identified for different varieties of suitable planting areas, or different areas suitable for planting varieties, in order to achieve high quality varieties of high quality production purposes.
