摘要:

为筛选适宜温州生态条件的高产、优质、抗病甘薯新品种(系),本研究以浙薯13为对照,对6个甘薯品种(系)进行田间品比试验,测定农艺性状、基腐病发病率、产量构成与品质指标。结果表明,所有参试品种(系)的基腐病发病率均极显著(p<0.01)低于对照,产量较对照增幅为10.52%~30.96%。其中,CP158表现最为突出,667 m2产量达3 125.67 kg,较对照增产30.96%,基腐病发病率最低(1.85%),食味总评分最高(78.5分),综合性状最优。CH60与西瓜红产量分别位列第二、三位。福薯604、济薯26和CJ3056产量中等,干物率和淀粉率较高,更适合淀粉加工。相关分析表明,产量与基腐病发病率呈极显著负相关。综上所述,CP158和CH60适合作为温州鲜食型甘薯推广种植,其余品种可根据品种特性差异化利用。

Abstract:

In order to screen new sweet potato varieties (lines) with high yield,good quality,and strong disease resistance suitable for the ecological conditions in Wenzhou,this study conducted a field comparative trial using Zheshu 13 as the control and evaluated six sweet potato varieties (lines),agronomic traits,resistance to basal rot,yield components,and quality indicators were measured. The results showed that the incidence rate of basal rot of all tested varieties (lines) was extremely significantly (p<0.01)lower than that of the control,with yield increases ranging from 10.52% to 30.96%. Among them,CP158 performed most prominently,with a 667 m2 yield of 3 125.67 kg,a yield increase of 30.96% compared with the control,the lowest incidence rate of basal rot (1.85%),and the highest total taste score (78.5 points),indicating optimal comprehensive traits. CH60 and Xiguahong ranked second and third in terms of yield,respectively. Fushu 604,Jishu 26 and CJ3056 showed moderate yields with high dry matter and starch rates,making them more suitable for starch processing. Correlation analysis revealed a highly significant negative correlation between yield and incidence rate of basal rot. In conclusion,CP158 and CH60 are suitable for promotion and cultivation as fresh-eating sweet potato varieties in Wenzhou,while the other varieties can be utilized differentially based on their variety characteristics.
