A method of breeding high soluble solids, high gloss, tylcv resistant cherry tomato inbred lines

Abstract

The invention discloses a method for cultivating cherry tomato inbred lines with high soluble solids, high gloss and TYLCV resistance. The material with high soluble solids content and high gloss obtained by continuous selfing of elite varieties with good taste and high gloss is self-crossed with varieties containing TYLCV resistance gene Ty‑2, and the F 2 Molecular marker-assisted selection of the anti-TYLCV gene was carried out to obtain homozygous single plants with anti-TYLCV genotype Ty-2 / Ty-2 and planted in the field. After the fruit matured, the soluble solids content and fruit gloss were mainly selected. to F 6 A cherry tomato inbred line with high fruit gloss, high soluble solids content and TYLCV resistance was bred for generations, and a new variety was obtained by crossing this inbred line with other inbred lines with higher yield. The invention provides a new breeding approach for the selection and breeding of tomato varieties, and can be popularized and applied in breeding and production.

Description

Technical field

[0001] The present invention relates to a method of cultivating high soluble solid, high gloss, anti-Tylcv's cherry tomato self-interaction, belonging to the field of plant breeding technology. Background technique

[0002] Solanum Lycopersicum is one of the world's important vegetable crops and economic crops, especially with the development of greenhouses and sunlight, the cultivation area is increasing. However, since 2005, the devastating disease spread from the tuniciki - tomato yellowed, virus, spread in my country, giving a heavy loss of tomato production in most of my country's property area, farmers planting tomato confidence receive a blow. The virus has sudden outbreaks, rapid expansion, strong harmful, and difficult to prevent and control, can only be solved by planting disease resistance varieties. At present, after many breeding units and company efforts have been made into a variety of tomato varieties of anti-Tylcv, solving the problem of difficult...
