高产优质双低杂交油菜品种'宜油46'的选育
Breeding of a Hybrid Rape Variety'Yiyou 46'with High Yield,Low Erucic Acid and Low Glucosinolates
摘要
Abstract
In response to the oilseed production capacity enhancement project and to empower the yield improvement initiatives for grain and oil crops,while persistently advancing the industrial development of rapeseed in Sichuan Province,we used the nuclear male sterility line'Yi 10AB'as female parent to cross with the restorer line'16-8007',a hybrid variety'Yiyou 46'with high yield and double-low(low erucic acid and low glucosinolates)was obtained after years of selection and identification.Its average yield in comparative experiment of new varieties in the Sichuan'Tianfu Rapeseed'for two consecutive years(2019-2021)was 3050.25 kg/hm2,8.1%higher than that of the control'Deyou 6'.The erucic acid content was 0.0371%,the glucosinolates content was 25.3 μmol/g,and the average oil content was 45.88%.'Yiyou 46'was a superior-quality variety with high yield,stable production,strong lodging resistance,excellent cold tolerance,robust disease resistance,wide adaptability,and suitability for mechanical harvesting.'Yiyou 46'was registered by the Ministry of Agriculture and Rural Affairs in 2022 with the registration number GPD Rapeseed(2022)510220 and recommended for autumn sowing in winter rapeseed cultivation areas of Sichuan's flatlands and hilly regions.关键词
