冬小麦新品种中梁34号是以兰天19号为母本、多亲杂交后代07709为父本杂交选育而成。该品种株高101.0 cm,穗长6.8 cm,千粒重48.75 g,容重782.0 g/L。2015 — 2017年参加甘肃省陇南片区域试验,2 a平均折合产量5 893.5 kg/hm2,较对照品种兰天19增产3.4%。2017 — 2018年参加生产试验,平均折合产量6 124.5 kg/hm2,较对照品种兰天19号增产4.0%。经接种鉴定,中梁34号苗期对条锈混合菌表现中感,成株期对中4-1、贵22-14、条中34号、条中33号、条中32号、贵农其他及混合菌等供试小种均表现免疫。适宜天水市及周边干旱和半干旱地区种植。

[Abstract]
Zhongliang 34 is a new winter wheat cultivar, bred from male parent of Lantian19 and femal parent 07709. The stem length is 101 cm, ear length 6.8 cm, 1000-grain weight 48.75 g, bluk weight 782.0 g/L. In 2015 — 2017, the average yield of Zhongliang 34 is 5 893.5 kg/hm2, Which is 3.4% higher than that of the check Lantian 19 in Longnan Winter Wheat Regional Test. In 2017 — 2018, the average yield of Zhongliang 34 reachers 6 124.5 kg/hm2, which is 4.0% higher than that of the check Lantian 19 in Longnan Winter Production Test. By inoculating identification, the results showed that Zhongliang 34 is moderate-susceptibility to mixture race at seedling stage, and immune to CY4-1,G22-14, CY34, CY33, CY32, Guinong strains and other mixture race at adult stage. It is suitable to be grown in Tianshui and arid and semi-arid region of surrounding areas.
