This paper presents obtained data on the natural background about tolerance of senior generations of cotton hybrids to bollworm (Helicoverpa armigera) with different levels of (+)-gossypol in seeds. It is discovered that the level of (+)-gossypol in seeds does not significantly show resistance to cotton ballwor. It confirmed possibility of selecting new sorts and lines of cotton with different levels (+)-gossypol and tolerance to bollworm. Genotypes with a low level of (+)-gossypol affected by bollworm is less to a certain extent than hybrids with high (+)-gossypol level.

Мақолада ғўза чигитидаги госсипол миқдорлари ва шаклларининг ғўза тунлами (Helicoverpa armigera) билан зарарланиш даражасига таъсири генетик-селекцион жиҳатдан асослаб берилган, турли миқдордаги ва шаклдаги госсиполга эга нав-намуналар иштирокида олинган дурагайларда ғўза тунламига бардошлиликнинг шаклланиши, чигитида (+)-госсипол миқдори ҳамда нисбатан ғўза тунламига бардошлилиги турлича бўлган селекцион ашёларни яратиш мумкинлиги келтирилган. Паст миқдордаги (+)-госсиполли генотиплар маълум даражада юқори миқдордаги (+)-госсиполли дурагайларга нисбатан камроқ зарарланганлиги аниқланди.

В статье представлены полученные в естественных условиях данные о толерантности старших поколений гибридов хлопчатника к хлопковому совку (Helicoverpa armigera) с различным уровнем (+)-госсипола в семенах. На основании полученных результатов выявлено, что уровень (+)-госсипола в семенах не обладает значительной устойчивостью к совку, т.е. подтверждена возможность отбора новых семей и линий хлопчатника с различными уровнями (+)-госсипола и толерантностью к совку. Генотипы с низким уровнем (+)-госсипола в определенной степени меньше поражались, чем гибриды с высоким (+)-госсиполом.
