马铃薯新品种黔芋9号的选育与应用研究
Breeding and Application of New Potato Variety Qianyu 9
摘要
Abstract
[Objective]New potato varieties with the advantages of high-yield,high-quality and disease resistance were bred to provide the support for high-quality development of potato industry.[Method]The excellent potato line was bred from the hybrid population constructed from the combination of Tacna ♀×Victoria ♂ by a systematic breeding method.[Result]The new bred potato line(No.09305-619)registered by Ministry of Agriculture and Rural Affairs in 2021 was named as Qianyu 9[Registration number:GPD Potato(2021)520110].Qianyu 9 was a medium maturing variety with the growth period of approximately 87 days(from emergence to maturity),semi-erect plant type,and average plant height of about 63 cm,resistance to potato virus X and potato virus Y,and moderate resistance to late blight.The dry matter,starch,protein,reducing sugar,vitamin C content in tubers of Qianyu 9 was 18.20%,14.84%,2.45%,0.05%and 17.20 mg/100g respectively.The tubers of Qianyu 9 with the advantages of low browning intensity,low browning index,less color change over time,and strong resistance to enzymatic browning was suitable for fresh-eating and fresh-cut processing.The average yield of Qianyu 9 was 2 104.35 kg/667m2 in 2019 and 2020,and 35.91%higher than Weiyu 5(CK).In 2022,the virus-free seed potato reproduction was further implemented.The average yield of Qianyu 9 in large-scale spring potato production demonstration tests in 2023 and 2024 was 3 857.65 kg/667m2 and 3 367.00 kg/667m2,respectively.The average yield of Qianyu 9 in winter potato production demonstration test in Changshun,Huishui,Huangping,Liping and Sandu Counties during 2023-2024 was 2 184.90 kg/667m2,and 21.74%higher than Favorita(CK).[Conclusion]Qianyu 9 with the advantages of good yielding ability,yield stability,lower reducing sugar content and good resistance to late blight should be popularized in the areas with medium and high altitudes of 800-2 600 m of Guizhou Province and in the areas with the similar ecological conditions.关键词
