Изобретение относитс к сельскому хозййству , а именно к селекции растений.The invention relates to agriculture, namely to plant breeding.
Известен способ оценки нематодоустойчивости томатов, заключающийс в искусственном заражении се нцев йцами нематод, которые раскладывают в стерилизованную почву посевных щиков па рассто нии 1 см от распикированного се нца.A known method for evaluating the nematode tolerance of tomatoes consists in artificially infecting the seedlings with nematode eggs, which are laid in sterilized soil of seedlings at a distance of 1 cm from the pickled seedling.

Целью изобретени вл етс повышение точности и ускорение процесса исследовани .The aim of the invention is to improve the accuracy and speed up the research process.
Дл этого определ ют содержание сс-томатина в корн х растений, по которому суд т о степени нематодоустойчнвости.For this purpose, the content of cs-tomatin in the roots of plants is determined, according to which the degree of resistance to nematode resistance is judged.
Способ основан на анализе корней се нцев в возрасте четырех-п ти недель, путем определени сс-томатина, по которому суд т о степени устойчивости к нематоде.The method is based on an analysis of the roots of the seedlings at the age of four to five weeks, by determining cc-tomatin, which is used to judge the degree of resistance to the nematode.
В результате исследовани поражеипых корней томатов установлено, что содержание сс-томатина пор дка 1% и выше на сухое вещество корней (см. таблицу) определ ет высоВосприимчивAs a result of a study of porous tomato roots, it has been established that the content of cc-tomatin, of the order of 1% or more per dry matter of the roots (see table), is highly susceptible

Данный способ оценки нематодоустойчивости по содержанию а-томатина в корн х се нцев значительно ускор ет и упрощает процесс определени нематодоустойчивости по сравнению с ранее известным. 3 Предмет изобретени Способ оценки нематодоустойчивости сортов томатов, отличающийс тем, что, с целью 4 повышени точности и ускорени njpouecea исследовани , определ ют содержание а-томатина в корн х растений, по которому суд т о степени нематодоустойчивости.This method of assessing nematode resistance by the content of a-tomato in the roots of seedlings considerably speeds up and simplifies the process of determining nematode resistance compared to the previously known one. 3 Subject of the Invention A method for evaluating the nematode tolerance of tomato varieties, characterized in that, in order to increase the accuracy and speed up the study njpouecea, the content of a-tomato in the roots of plants is determined, which is judged by the degree of nematode resistance.
