Phosphorus (P), a crucial nutrient, has a significant impact on the growth, development, and productivity of sweetpotato. Establishing an evaluation system for low-phosphorus tolerance in sweetpotato and screening for low-phosphorus tolerant sweetpotato varieties can provide essential foundational support for the further development, breeding, and utilization of low-phosphorus tolerant sweet potato resources. In this study, 30 sweet potato varieties were selected. Field experiments with phosphorus deficiency were conducted, involving two phosphorus treatment conditions, no phosphorus application (0 kg/hm2) and normal phosphorus supply (110 kg/hm2). At the harvest stage, 14 characteristic traits were measured, including fibrous root fresh weight, lateral root of storage root fresh weight, single storage root fresh weight, storage root fresh weight per plant, storage root number per plant, fibrous root dry weight, lateral root of storage root dry weight, storage root dry weight, leaf fresh weight, stem fresh weight, leaf dry weight, stem dry weight, relative chlorophyll content and root/shoot ratio. The low-phosphorus tolerance coefficient for each index was calculated. Principal component analysis, correlation analysis, and cluster analysis were performed using the comprehensive membership function method to evaluate the low-phosphorus tolerance of each sweet potato cultivar. Principal component analysis showed that the cumulative variance contribution rate of the five principal components reached 80.36%, indicating these indicators fully reflected the low-phosphorus tolerance of sweetpotato varieties. The comprehensive low-phosphorus tolerance evaluation value (D) was calculated via the membership function method, with D values ranging from 0.30 to 0.79. The varieties were classified into four grades, high tolerance, medium tolerance, low tolerance, and non-tolerance. Through systematic cluster analysis, Qiongshu4 was identified as a high-tolerance variety, Silky, Fushu8, and Shanchuanzi were classified as medium-tolerance varieties, Yanshu25, Taishu14, and Xuzishu8 were low-tolerance varieties, and Annayu, Jinshu17, and Xinxiang were low phosphorus-sensitive varieties. The key evaluation indicators for low-phosphorus tolerance in sweet potato at harvest stage were determined to be the yield per plant (storage root fresh weight per plant), fibrous root fresh weight, lateral root of storage root fresh weight, fibrous root dry weight, leaf fresh weight, stem fresh weight, leaf dry weight, and stem dry weight. This study would provide a theoretical basis for breeding and utilizing new low-phosphorus-tolerant sweetpotato varieties.

磷(P)是影响甘薯生长发育与生产力的关键营养元素之一。建立甘薯耐低磷能力评价体系并筛选耐低磷品种,可为后续甘薯耐低磷资源的创制与育种利用奠定基础。本研究选取30个甘薯品种,在低磷大田中设置不施磷(0 kg/hm2)和正常供磷(110 kg/hm2)处理,测定甘薯收获期的纤维根鲜质量、块根侧根鲜质量、单个块根鲜质量、单株块根鲜质量、单株块根数、纤维根干质量、块根侧根干质量、块根干质量、叶鲜质量、茎鲜质量、叶干质量、茎干质量、叶绿素相对含量和根冠比14个性状表征值,并计算各指标的耐低磷系数。在此基础上,运用隶属函数法进行主成分分析、相关性分析和聚类分析,评估各品种的耐低磷能力。研究结果表明:通过主成分分析,5个主成分的累计方差贡献率达到了80.36%,表明这些指标能够全面反映甘薯品种的耐低磷能力。利用隶属函数法计算出综合耐低磷评价值(D),D值范围为0.30~0.79,据此将甘薯品种划分为高耐、中耐、低耐和不耐4个等级。经过系统聚类分析,筛选出琼薯4号为高耐低磷型甘薯品种;丝滑、福薯8号和山川紫等为中耐低磷型甘薯品种;烟薯25、泰薯14和徐紫薯8等为低耐低磷型甘薯品种;安娜芋、金薯17和心香3个品种为低磷敏感型甘薯品种;确定单株产量(即单株块根鲜质量)、纤维根鲜质量、块根侧根鲜质量、纤维根干质量、叶鲜质量、茎鲜质量、叶干质量和茎干质量可作为甘薯收获期耐低磷能力评价的指标。本研究可为耐低磷型甘薯新品种选育及利用提供理论依据。

磷(P)是影响甘薯生长发育与生产力的关键营养元素之一。建立甘薯耐低磷能力评价体系并筛选耐低磷品种,可为后续甘薯耐低磷资源的创制与育种利用奠定基础。本研究选取30个甘薯品种,在低磷大田中设置不施磷(0 kg/hm2)和正常供磷(110 kg/hm2)处理,测定甘薯收获期的纤维根鲜质量、块根侧根鲜质量、单个块根鲜质量、单株块根鲜质量、单株块根数、纤维根干质量、块根侧根干质量、块根干质量、叶鲜质量、茎鲜质量、叶干质量、茎干质量、叶绿素相对含量和根冠比14个性状表征值,并计算各指标的耐低磷系数。在此基础上,运用隶属函数法进行主成分分析、相关性分析和聚类分析,评估各品种的耐低磷能力。研究结果表明:通过主成分分析,5个主成分的累计方差贡献率达到了80.36%,表明这些指标能够全面反映甘薯品种的耐低磷能力。利用隶属函数法计算出综合耐低磷评价值(D),D值范围为0.30~0.79,据此将甘薯品种划分为高耐、中耐、低耐和不耐4个等级。经过系统聚类分析,筛选出琼薯4号为高耐低磷型甘薯品种;丝滑、福薯8号和山川紫等为中耐低磷型甘薯品种;烟薯25、泰薯14和徐紫薯8等为低耐低磷型甘薯品种;安娜芋、金薯17和心香3个品种为低磷敏感型甘薯品种;确定单株产量(即单株块根鲜质量)、纤维根鲜质量、块根侧根鲜质量、纤维根干质量、叶鲜质量、茎鲜质量、叶干质量和茎干质量可作为甘薯收获期耐低磷能力评价的指标。本研究可为耐低磷型甘薯新品种选育及利用提供理论依据。

Phosphorus (P), a crucial nutrient, has a significant impact on the growth, development, and productivity of sweetpotato. Establishing an evaluation system for low-phosphorus tolerance in sweetpotato and screening for low-phosphorus tolerant sweetpotato varieties can provide essential foundational support for the further development, breeding, and utilization of low-phosphorus tolerant sweet potato resources. In this study, 30 sweet potato varieties were selected. Field experiments with phosphorus deficiency were conducted, involving two phosphorus treatment conditions, no phosphorus application (0 kg/hm2) and normal phosphorus supply (110 kg/hm2). At the harvest stage, 14 characteristic traits were measured, including fibrous root fresh weight, lateral root of storage root fresh weight, single storage root fresh weight, storage root fresh weight per plant, storage root number per plant, fibrous root dry weight, lateral root of storage root dry weight, storage root dry weight, leaf fresh weight, stem fresh weight, leaf dry weight, stem dry weight, relative chlorophyll content and root/shoot ratio. The low-phosphorus tolerance coefficient for each index was calculated. Principal component analysis, correlation analysis, and cluster analysis were performed using the comprehensive membership function method to evaluate the low-phosphorus tolerance of each sweet potato cultivar. Principal component analysis showed that the cumulative variance contribution rate of the five principal components reached 80.36%, indicating these indicators fully reflected the low-phosphorus tolerance of sweetpotato varieties. The comprehensive low-phosphorus tolerance evaluation value (D) was calculated via the membership function method, with D values ranging from 0.30 to 0.79. The varieties were classified into four grades, high tolerance, medium tolerance, low tolerance, and non-tolerance. Through systematic cluster analysis, Qiongshu4 was identified as a high-tolerance variety, Silky, Fushu8, and Shanchuanzi were classified as medium-tolerance varieties, Yanshu25, Taishu14, and Xuzishu8 were low-tolerance varieties, and Annayu, Jinshu17, and Xinxiang were low phosphorus-sensitive varieties. The key evaluation indicators for low-phosphorus tolerance in sweet potato at harvest stage were determined to be the yield per plant (storage root fresh weight per plant), fibrous root fresh weight, lateral root of storage root fresh weight, fibrous root dry weight, leaf fresh weight, stem fresh weight, leaf dry weight, and stem dry weight. This study would provide a theoretical basis for breeding and utilizing new low-phosphorus-tolerant sweetpotato varieties.
