为选育适宜甘肃陇南麦区及同类地区推广种植的抗病、丰产且适应性广的冬小麦品种，天水市农业科学研究所以自育高代品系00127-2-2-3作母本、周麦22号作父本配制杂交组合，经多年多点连续鉴定选择，培育成了抗条锈高产冬小麦新品种天选79号。2019 — 2021年参加甘肃省陇南片川区组区域试验，2 a 10点(次)平均折合产量7 437.90 kg/hm2，较对照品种兰天33号增产6.87％。2021 — 2022年度参加生产试验，5点(次)平均折合产量6 910.35 kg/hm2，较对照品种兰天33号增产3.25%。该品种株高78.4 cm，穗长8.0 cm，每穗粒数40.96 粒，籽粒白色，硬质，千粒重46.31 g，有效穗数570 万穗/hm2。具有抗条锈、稳产、抗倒伏、籽粒品质优良等特点，适宜在甘肃省天水渭河川道区及陇南麦区低海拔区种植。

In order to breed winter wheat varieties with disease resistance, high yield and wide adaptability suitable for planting in Longnan wheat area and similar areas in Gansu Province, Tianshui Institute of Agricultural Sciences carried out sexual hybridization with self-bred line 00127-2-2-3 as female parent and Zhoumai 22 as male parent. After years of continuous pedigree selection of hybrid offspring, a new winter wheat variety Tianxuan 79 with high yield and resistance to stripe rust was bred. During 2019 — 2021, it participated in the regional test of Longnan area in Gansu Province. The average yield of 10 points in 2 years was 7 437.90 kg/ha, which was 6.87 % higher than that of the control variety Lantian 33. From 2021 to 2022, data from the production test showed that the average yield of 5 pilot sites was 6 910.35 kg/ha, which was 3.25 % higher than that of the control variety Lantian 33. The plant height of this variety is 78.4 cm, the panicle length is 8.0 cm, the number of grains per panicle is 40.96, the grains are white and hard, the 1000-grain weight is 46.31 g, and the number of effective panicles is 5.7 million/ha. It has the characteristics of stripe rust resistance, stable yield and lodging resistance, and is suitable for planting in the low altitude areas of the Weihe River channel area in Tianshui, Gansu Province and the wheat area in Longnan.
