Abstract

The invention discloses a method for cultivating a cherry tomato inbred line with high soluble solids, high gloss and TYLCV resistance. The method comprises the steps of selfing a material with high soluble solid content and high gloss obtained by continuous selfing of excellent varieties with good mouthfeel and high gloss with TYLCV resistance genes Ty-2, performing molecular marker assisted selection against TYLCV genes on the F2 generation to obtain homozygous individuals with an anti-TYLCV genotype Ty-2 / Ty-2, planting the homozygous individuals in the field, selecting main individuals withhigh soluble solid content and high fruit gloss after fruits are ripened, selecting a cherry tomato inbred line with high fruit gloss, high soluble solid content and TYLCV resistance at the F6 generation, and hybridizing the inbred line with other inbred line with high yield to obtain a new variety. The method provides a novel breeding route for breeding of tomato varieties, and can be popularized and applied in breeding and production.

Description

technical field

[0001] The invention relates to a method for cultivating cherry tomato inbred lines with high soluble solids, high gloss and TYLCV resistance, and belongs to the technical field of plant breeding. Background technique

[0002] Tomato (Solanum lycopersicum) is one of the important vegetable crops and economic crops in the world, especially with the development of greenhouses and solar greenhouses, the cultivation area continues to increase. However, since 2005, the devastating disease transmitted by Bemisia tabaci - tomato yellow leaf curl virus disease has spread in a large area in my country, causing heavy losses to tomato production in most of the main tomato producing areas in my country, and farmers have great confidence in planting tomatoes receive a blow. The virus has the characteristics of sudden outbreak, rapid expansion, strong harm, and difficulty in prevention and control, which can only be solved by planting disease-resistant varieties. At prese...
