摘　　要：本研究旨在培育黑龙江省良食味稻米生产亟需的高产优质中熟水稻新品种。在水稻‘吉粳88’×导入系‘稻花香2号(hd2hd4)’后代中,分子标记和田间性状选择相结合培育符合育种目标的水稻品种。水稻‘吉粳88’具有株型直立、抗倒伏、高产和Hd2Hd2Hd4Hd4抽穗期基因型及晚熟等特征,导入系‘稻花香2号(hd2hd4)’具有香味、适口性好和hd2hd2hd4hd4基因型及早熟等性状。从‘吉粳88’ב稻花香2号(hd2hd4)’的杂交后代材料中,培育了具有hd2hd2Hd4Hd4fgrfgr基因型、主茎叶片13片、茎叶直立、抗倒伏、高产、有香味、适口性好的水稻新品系,命名为‘黑大香1’。‘黑大香1’农艺性状优良,可用于黑龙江省第1积温区下限良食味稻米生产。The purpose of this study is to cultivate new rice varieties with characteristics of high yield, good quality and middle maturing date, which are urgently needed in good taste rice production in Heilongjiang Province. Rice varieties meeting requirements of the breeding objectives were bred with the combination of molecular marker and field trait selection from generations of‘Jijing88’× the introgression line‘Daohuaxiang2(hd2hd4)’.‘Jijing88’had the traits of erected plant type, lodging resistance, high yield, Hd2Hd2Hd4Hd4 genotype of heading date and late maturing, and the introgression line‘Daohuaxiang2(hd2hd4)’possessed the characteristics of fragrance, good palatability, hd2hd2hd4hd4 genotype and early maturing. A new rice line,which was hd2hd2Hd4Hd4 fgrfgr genotype, with 13 leaves of main stem, erected stem-leaf, lodging resistance,high yield, fragrance and good palatability, was bred based on offspring materials of the combination of‘Jijing 88’בDaohuaxiang2(hd2hd4)’. It was named‘Heidaxiang1’. The rice‘Heidaxiang1’with better agronomic characteristics could be used for good taste rice production in the lower limit of the first accumulated temperate region of Heilongjiang Province.
