摘　　要：以抗番茄黄化曲叶病毒病自交系为抗病供体,以粉果优良自交系为轮回亲本,经过杂交、回交,结合分子标记辅助选择和四代田间自交分离选择,选育出抗番茄黄化曲叶病毒病、综合性状优良的粉果番茄新品系2019113。其果实圆形,成熟果粉红色,色泽鲜艳,平均单果质量160 g,上下层果实整齐均匀,耐贮运。分子水平检测基因型为TY-2/TY-2,含Ty-2纯合抗病基因,田间未发现黄化曲叶病毒病,抗叶霉病,综合性状优良。A new tomato line 2019113 of pink fruit tomato with good comprehensive characters was bred by using the cultivars with resistance to TYLCV as the disease-resistant donor and the superior pink fruit cultivars as the recurrent parents after crossing and backcrossing,which combined with molecular marker assisted selection and four generations of field self crossing and separation selection. The fruit is round,the ripe fruit is pink and bright in color,the average single fruit quality is 160 g,the upper and lower fruits are uniform in size,and the storage and transportation are good. The genotype detected at the molecular level is Ty-2/Ty-2,which contains the Ty-2 homozygous disease-resistant gene. There is no yellow curve leaf virus disease and leaf mildew resistance in the field,and the comprehensive characteristics are excellent.
