通过对131个性状基本稳定的优良品系进行田间观察筛选,淘汰115个田间表现较差品系,实收18个品系进行产量及外观品质分析,并对其抗病性、抗逆性、丰产性等经济性状综合鉴定。其中2015鉴13、2015鉴68、2015鉴70产量较高分别居第一、二、三位,较邻近对照品种分别增产32.28﹪、18.07﹪、16.57﹪,其中2015鉴68属粳型软米、米饭食味佳、冷不回生;2015鉴70稻米外观好、米饭香、不回生;2015鉴32稻米外观品质较好、食味佳。确定4个品系可在云南1500~1 850m海拔稻区进行多点试验确定其适应性。
Through field observation and screening of 131 fine lines with basically stable characters, we eliminated 115 lines with poor performance, 18 lines were collected for yield and quality analysis, and their resistance, resistance, high yield and so on Comprehensive evaluation of economic traits. Among them, 2015 survey 13,2015 survey 68,2015 survey 70 yield higher respectively ranked first, second and third place, respectively 32.28%, 18.07%, 16.57% compared with neighboring control varieties, of which 2015 Kam 68 is japonica soft rice, Good taste of rice, cold does not come back; 2015 Kam 70 rice looks good, rice fragrant, not back; 2015 Kam 32 rice look better quality, good taste. Four strains were identified in the 1500 ~ 1850m altitude rice areas in the multi-point test to determine its adaptability.
