Breeding and Application of Qianqing 5,a New Leaf Mustard Cultivar
摘要
Abstract
[Objective]A new leaf mustard variety with the advantages of high-yield,high-quality and good stress resistance was bred to meet the needs of the leaf mustard variety market.[Method]The new leaf mustard variety was bred from Qinglong Chinese cabbage(a local drought-resistance material)by using the microspore technology for purification and rejuvenation and screening the excellent DH line.[Result]Qianqing 5,a new leaf mustard variety with good drought tolerance,high plant uniformity,strong stress resistance,growth period of 170 d and medium maturation was approved by Guizhou Non-major Crops Variety Examination Committee(No.:Qianrenshu 20220026)in 2023.The suitable sowing period of Qianqing 5 was from August to October.The average yield of Qianqing 5 was 4 590.70 kg/667m2 in 5 production test sites of Huaxi,Dushan,Weining,Xifeng and Qinglong during 2016-2017,14.2%and 9.3%higher than that of Qiangqing 1(CK1,4 018.30 kg/667m2)and Qianqing 2(CK2,4 199.60 kg/667m2),respectively.The water,VC,soluble sugar,total free amino acid,soluble protein,Ca,P and Fe content and cellulose mass fraction in fresh leaves of Qiangqing 5 were 93.28%,60.43 mg/100g,4.86%,0.20 mg/g,2.08 g/100g,276.67 mg/kg,329.00 mg/kg,3.99 mg/kg and 22.56 mg/g,respectively.Qianqing 5 with smooth leaf surface,light green leaves,deeply lobed leaf edges,narrow and long petioles has the advantages of low crude fiber content,rich nutrition,good brittleness and excellent economic traits.[Conclusion]Qianqing 5 with high-yield,high-quality and strong resistance is suitable for processing and fresh-eating.Qianqing 5 should be cultivated in Central Guizhou,South Guizhou and Southwest Guizhou areas with an altitude of 900-1 300 meters and other similar ecological areas.关键词
