鲜食型马铃薯新品种克新35的选育及栽培技术
Breeding and Cultivation Technology of New Fresh Potato Variety Kexin 35
摘要
Abstract
In order to promote the popularization and application of new potato variety Kexin 35,the breeding processs,variety charactestics,yielity,quality,disease resistance and cultivation techniques of Kexin 35 were briefly introduced in this paper.Kexin 35 was bred by Kexin 22 as female parent and Kexin 16 as male parent through sexual hybridization,selection and identification.From 2019 to 2020,Kexin 35 participated in regional trial,the average total yield was 2 273.16 kg·(667 m2)-1,which was increased by 6.40％compared to the control Kexin 13.From 2021 to 2022,Kexin 35 participated in production trial,the average total yield was 2 345.70 kg·(667 m2)-1,which was increased by 12.20％compared to the control Kexin 13.In 2023,it was registered as a non staple crop variety by the Ministry of Agriculture and Rural Affairs,with the registration number GPD Potato(2023)230013.The variety was medium maturing with 82 days of growth period(from emergence to maturity).The plant type was semi erect and plant height was about 45.1 cm.The tubers were round and yellow skin,light yellow flesh,medium bud eyes,and the commercial tuber rate was 78.00％,dry matter content was 21.9 g·(100 g)-1,starch content was 16.6 g·(100 g)-1,protein content was 2.21 g·(100 g)-1,VC content was 38.2 mg·(100 g)-1,and reducing sugar content was 0.58 g·(100 g)-1.It is moderately resistant to late blight,PVX and PVY virus.It is suitable for planting in various ecological areas of Heilongjiang Province.关键词
