水稻是中国重要的粮食作物之一,而选育优质、多抗、高产的水稻新品种在生产生活中有重要的作用。水稻新品种‘吉农大138’是经人工有性杂交,以自选系‘158’为父本、‘吉粳83’为母本,采用系谱法选育而成。两年区域试验平均产量为9 400.2 kg/hm2,比对照品种‘通35’增产7.0%,一年生产试验平均产量为9 138.9 kg/hm2,比对照品种‘通35’增产6.5%。水稻新品种‘吉农大138’具有米质好、高产稳产、抗逆性强、农艺性状好、活秆成熟等优点,于2017年通过吉林省农作物品种审定委员会审定。该品种适宜中晚熟稻区种植,如吉林省的长春、四平、松原、吉林、辽源等。水稻新品种‘吉农大138’应用前景十分广阔,社会经济效益十分显著,对推进农业供给侧改革,实现农业增效,农民增收起到较大的促进作用。
Rice is one of the most important food crops in China, and the breeding of new rice varieties with high quality, multi-resistance and high yield is quite important in production and life. The new rice variety ＇Jinongda 138＇was obtained through artificial sexual hybridization, with self-selection inbred line ＇158＇ as the male parent and ＇Jijing83＇ as the female parent based on pedigree method. For 2-year regional trials, the average output was 9 400.2 kg/hm2,which was 7.0% higher than the control variety ＇Tong 35＇. For 1-year productive trials, the average output was 9138.9 kg/hm2, and it was 6.5% higher than the control variety ＇Tong 35＇. ＇Jinongda 138＇ had the advantages of good quality, high and stable yield, strong resistance, good agronomic traits and straw stay green, which was examined and approved by Jilin Evaluation Committee of Crop Variety in 2017. It was suited to be planted in the middle and late maturing rice regions, such as Changchun, Siping, Songyuan, Jilin and Liaoyuan in Jilin. The application prospects of＇Jinongda 138＇ is broad and the social and economic benefits are remarkable, which could play a great role in promoting agricultural supply-side reform, realizing agricultural efficiency and increasing farmers＇ income.
