TOMATO PLANTS POSSESSING HIGH LEVEL OF BOTRYTIS RESISTANCE Russian patent published in 2012 - IPC C12N15/82 A01H1/06 A01H5/08 A01H5/10 C12Q1/68 

FIELD: medicine.

SUBSTANCE: what is described is a method for producing Botrytis-resistant tomato involving a) producing Botrytis-resistant donor tomato plant preferentially of S. Habrochaites species or S. habrochaites LYC 4/78 line, b) transfer of nucleic acid from said donor plant into one or more Botrytis-sensitive recipient tomato plants, c) selection among the recipient tomato plant of the one containing at least one quantitative trait locus (QTL) in a genome for Botrytis-resistance from said Botrytis-resistant donor plant wherein said selection involves detection of one genetic marker related to said at least one QTL for Botrytis-resistance on 4, 6, 9, 11 and/or 12 chromosome of said recipient tomato plant. What is presented is a method for producing the inbred tomato plant involving breeding of Botrytis-resistant tomato plant with the same plant or the other tomato plant. Besides, there are described DNA produced from the tomato plant of S. lycopersicum species, containing QTL specified in a group consisting of QTL on chromosomes 4, 6, 9, 11 and 12 Solarium habrochaites LYC 4/78; Botrytis-resistant tomato plant and Botrytis-resistant portion of the tomato plant. What is also presented is a method for detection of QTL for Botrytis resistance involving detection of at least one genetic marker coupled with QTL for Botrytis resistance formed of S. habrochaites LYC 4/78 on 4, 6, 9, 11 and/or 12 chromosome. What is presented is the use of the genetic marker specified in a group consisting of the genetic markers presented in Tables 1-5 in the description for detection of QTL for Botrytis resistance.

EFFECT: invention provides producing Botrytis-resistant tomato plant.
