保健型遗传工程稻三号(GER—3)是湖南农业大学万文举副教授为主的课题组,将玉米部分 DNA 片断导入水稻,并对受体产生的广泛变异进行多代定向选育而成。今年在湖南大面积推广试种,亩产都超过杂交水稻,在云南省永胜县涛源乡试种攻关田,面积为1.048亩,由云南省科委、农科院、省种子公司,云南农大以及湖南省农科院、农大和丽江地区农科所的专家学者组成的专家小组在涛源乡进行现场考察和验收,每亩有效穗33.77万,每穗总粒数137.84粒,实粒数127.33粒,结实率92.36%,千粒重25克,实际验收亩产1062.01公斤。该品种1993年10月22日已通过国内著名专家组成的鉴定委员会鉴定。GER—3通过大面积试种,生育期比汕优63早熟4～5天,株高120厘米左右,分蘖力强,株型紧凑,叶窄而直立,生长青秀而整齐,丰产性好,不需要年年制
Health-based Genetic Engineering Rice III (GER-3) is a research group led by Associate Professor Wan Wenju from Hunan Agricultural University. Some DNA fragments of maize were introduced into rice and the mutants of multiple generations were selected for selective breeding . This year in Hunan large-scale promotion of trial planting, mu produce more than hybrid rice, Yongsheng County, Yunnan Province, Tao Yuan Township try seed attack Gutian, an area of 1.048 acres, the Yunnan Provincial Science and Technology Commission, Academy of Agricultural Sciences, the provincial seed company, Yunnan Agricultural University And experts from Hunan Academy of Agricultural Sciences, Agricultural University and Lijiang region experts and scholars in the field of Tao Yuan Township site inspection and inspection, the effective panicle per acre 337,700, the total number of grains per panicle 137.84, the real number of 127.33 Grain, seed set rate 92.36%, grain weight 25 grams, the actual acceptance of 1062.01 kilograms per mu. The species October 22, 1993 has passed the appraisal committee composed of famous experts appraisal. GER-3 through a large area of trial, the growth period than the Shanyou 63 precocious 4-5 days, about 120 cm tall, strong tillering ability, plant compact, narrow and upright leaves, growing green show neat, good yield, Do not need annual system
