摘要
【目的】为满足鲜食玉米生产对优质早熟甜糯新品种的迫切需求。【方法】2016年以自选糯质玉米自交系NF10作母本,以自选甜质玉米自交系NF11作父本进行优质、早熟甜糯玉米新品种选育。【结果】2020年育成甜糯型鲜食玉米新品种桂甜糯987,该品种在2019年广西鲜食糯玉米区试中,春季平均鲜果穗产量11662.5 kg/hm^(2),较对照(桂糯519)增产16.8%,增产点次100%;秋季平均鲜果穗产量11694.0 kg/hm^(2),较对照(桂糯519)增产14.7%,增产点次100%;两季平均鲜果穗产量11679.0 kg/hm^(2),较相邻对照增产15.8%,春秋两季参试14点全部较对照增产,增产点次100%。【结论】该品种2020年6月通过广西农作物品种审定委员会审定(桂审玉2020041号),具有果穗粗长、籽粒饱满、黄白粒、柔嫩、皮薄、脆甜、口感好、早熟、综合抗性好等特点,适宜广西及类似生态区域种植。
【Objective】The purpose of the study is to meet the urgent demand of new sweet waxy corn varieties with high-quality and early-maturity in the production of fresh-eating corn.【Method】The breeding of new sweet waxy corn variety with high-quality and early-maturity is carried out by taking self-selected waxy corn inbred line NF10 as female parent and self-selected sweet corn inbred line NF11 as male parent.【Result】Guitiannuo 987,a new sweet-waxy fresh-eating corn variety,was successfully bred in 2020.In regional test of Guangxi fresh-eating corn in 2019,the average yield of fresh ear in spring is 11662.5 kg/hm^(2),16.8%higher than CK(Guinuo 519)and the sites with yield increase reach 100%;The average yield of fresh ear in autumn is 11694.0 kg/hm^(2),14.7%higher than CK(Guinuo 519)and the test sites with yield increase reach 100%;The average yield of fresh ear in spring and autumn is 11679.0 kg/hm^(2),15.8%higher than near contrasts,and the yield of 14 test sites all increases compared with CK,the sites with yield increase reach 100%.【Conclusion】The variety was approved by Guangxi Crop Variety Approval Committee(Guishenyu 2020041)in June,2020.Guitiannuo 987 is featured with thick and long ears,filling grain,yellow-white grain,tender,thin coat,crisp and sweet,good taste,early maturity and excellent comprehensive resistance,which is suitable for cultivation in Guangxi and similar ecological areas.
