Improved Tomato Lines: Muchamiel, De la Pera, Cherry and Virus-Resistant Hybrids<\/h1>\n

Several improved lines of Muchamiel, De la pera, Cherry and hybrids with genetic resistance to ToMV, TSWV and TYLCV have been obtained, three of the viruses that most affect tomato crops in south-eastern Spain.<\/h2>\n<\/header>\n\n\n\n

TECHNOLOGY DESCRIPTION<\/h3>\n
\n

As part of the Traditional Tomato Variety Improvement Programme being developed at CIAGRO-UMH since 1998, several lines of Muchamiel, De la pera, Cherry and hybrids with genetic resistance to some of the most important viral diseases affecting tomato crops in south-eastern Spain have been obtained: Tomato mosaic virus (ToMV), Tomato yellow leaf curl virus (TYLCV) and Tomato spotted wilt virus (TSWV). The new lines obtained have agronomic, quality and functional characteristics similar to those of the original traditional varieties, together with resistance to ToMV and TSWV and tolerance to TYLCV. The following table details the resistance of each of the lines obtained:<\/p>\n
