摘要:

宁春66号是宁夏农林科学院农作物研究所和中国农业科学院作物科学研究所共同选育的春小麦新品种,该品种以宁春50号为母本与含有簇毛麦中高抗白粉病基因Pm21的春小麦品系CB037为父本进行杂交,选择含有Pm21基因或表现白粉病抗性且农艺性状优良的目标单株与宁春50号回交5次,对稳定自交后代进行白粉病抗性鉴定、分子标记辅助选择和基因组原位杂交(GISH)等,经系统选育获得了含有Pm21基因且田间表现高抗白粉病、农艺性状优良的新品系NZ42,然后进行多年多点产量评价,于2022年9月通过宁夏回族自治区农作物品种审定委员会审定,命名为宁春66号。该品种具有高产、优质、广适和高抗白粉病等特点,且适合轻简化栽培。

Abstract:

Ningchun 66 is a new spring wheat variety developed by the Institute of Crop Sciences of Ningxia Academy of Agriculture and Forestry Sciences and the Institute of Crop Sciences of Chinese Academy of Agricultural Sciences in collaboration. In its breeding program, a spring wheat variety Ningchun 50 was used as the female parent to be crossed with a spring wheat line CB037 containing the powdery mildew resistance gene Pm21 from Haynaldia villosa, and the hybrid plants harboring Pm21 or showing powdery mildew resistance and displaying good agronomic traits were backcrossed with Ningchun 50 for five times. The identification of powdery mildew resistance, molecular marker-assisted selection and genomic in situ hybridization (GISH) of stable self-crossing offsprings, an excellent line NZ42 with Pm21 gene, high resistance to powdery mildew, and excellent agronomic traits in the field conditions were systematically bred via pedigree method and evaluated for yield performance in different years and different regions, which was approved and named as Ningchun 66 in 2022 September by the Crop Examination Committee of Ningxia Hui Autonomous Region. This variety features high yield, excellent quality, wide adaptability and high resistance to powdery mildew, and is suitable for simplified cultivation.

Key words: Spring wheat, Molecular marker-assisted selection, Powdery mildew, Backcross breeding, Ningchun 66
