【摘要】 旨在选育广适、多抗、高产、优质的玉米新品种。以自选糯玉米自交系“LN1520”为母本、双隐性玉米自交系“LTN2017”为父本测配杂交组合，参加区域试验。结果显示，“柳甜糯209”在2022年广西糯玉米区域试验中，春季平均鲜果穗产量为811.7 kg/667 m~2，比对照增产8.5%，增产点次86%；秋季平均鲜果穗产量为811.3 kg/667 m~2，比对照增产8.4%，增产点次100%；两季平均鲜果穗产量为811.5 kg/667 m~2，比相邻对照增产8.4%，在春秋两季参试的14点中，有13点比对照增产，增产点次93%。在2022年广西鲜食糯玉米品种区域试验中，空杆率为2.5%；双穗率为1.0%；保绿度为89%；分蘖率为6.7%；田间记载大斑病1—3级，平均1.9级；小斑病1—3级，平均1.5级；纹枯病病情指数为0～32.0，平均7.2；青枯病为0；茎腐病为0～7.9%，平均0.8%；南方锈病1—7级，平均2.6级。由此可知，“柳甜糯209”属于中熟品种、植株形态理想、抗逆能力强、产量高、品质优，适合在广西及周边地区推广种植。本研究为鲜食玉米种植提供品种选择和栽培技术参考。更多还原

【Abstract】 This study aimed to breed new corn varieties that are widely adaptable, multi-resistant, highyielding and of high quality. The hybrid combination was developed by crossing the selected glutinous corn inbred line "LN1520" as the female parent with the double recessive corn inbred line "LTN2017" as the male parent, and it participated in the regional trials. The results showed that in the 2022 Guangxi regional trials of glutinous corn, "Liu Tian Nuo 209" had an average fresh ear yield of 811.7 kg/667 m~2 in spring, an increase of 8.5% over the control, with an increase rate of 86%; in autumn, the average fresh ear yield was 811.3 kg/667 m~2, an increase of 8.4% over the control, with an increase rate of 100%; the average fresh ear yield over the two seasons was 811.5 kg/667 m~2, an increase of 8.4% over the adjacent control. Among the 14 test sites in spring and autumn, 13 sites had higher yields than the control, with an increase rate of 93%. In the 2022 regional test of fresh glutinous corn varieties in Guangxi, the rate of missing ears was 2.5%; the rate of double ears was 1.0%; the green retention rate was 89%; the number of tillers was 6.7%; the severity of major spot diseases ranged from 1 to 3 levels in the field, with an average of 1.9 levels; the severity of minor spot diseases ranged from 1 to 3 levels, with an average of 1.5 levels; the lesion index of sheath blight was 0 to 32.0, with an average of 7.2; bacterial wilt was 0; stem rot was 0 to 7.9%, with an average of 0.8%; southern rust ranged from 1 to 7 levels, with an average of 2.6 levels. It can be concluded that “Liu Tian Nuo 209” is a mid-maturing variety with an ideal plant morphology, strong adaptability and resistance, high yield, and excellent quality. It is suitable for promotion and cultivation in the Guangxi region and its surrounding areas. This study provides reference for variety selection and cultivation techniques in the production of fresh corn.更多还原
