The New Mexico Agricultural Experiment Station announces the release of upland cotton (Gossypium hirsutum L.) cultivar ‘Acala 1517‐21’ (Reg. no. CV‐144, PI 693757). Acala 1517‐21 was derived from a single plant selection in F₃ from a bi‐parental cross between LA05307029 and AU‐5491. This new cultivar was tested in eight replicated field trials in New Mexico in 2012–2017 and 21 tests across 12 states of the Cotton Belt in 2016–2017. In New Mexico, Acala 1517‐21 yielded similarly to medium‐staple cultivars or transgenic commercial Acala cultivars including ‘PHY 725 RF’, ‘PHY 755 WRF’, ‘PHY 764 WRF’, ‘FM 2322GL’, and ‘FM 1830GLT’. Compared with ‘Acala 1517‐08’, Acala 1517‐21 averaged 12.9% higher lint yield and 11.5% higher lint percentage, with a similar boll weight, fiber length, length uniformity, elongation, micronaire, and short fiber content. However, Acala 1517‐21 had similar or slightly lower fiber strength with significantly lower strength and elongation in one test. Compared with commercial transgenic and nontransgenic cultivars across the Cotton Belt, Acala 1517‐21 had consistently longer and stronger fibers or lower micronaire readings. Acala 1517‐21 represents a high‐yielding upland cotton cultivar with high lint percentage and a long staple.

注册“ Acala 1517-21”棉花品种

新墨西哥州农业实验站宣布释放陆地棉（Gossypium hirsutum L.）品种'Acala 1517-21'（Reg。no。CV-144，PI 693757）。Acala 1517-21来自F _3中的单一植物选择来自LA05307029和AU‐5491之间的双亲杂交。2012-2017年在新墨西哥州进行了八项重复田间试验，并于2016-2017年在棉带12个州进行了21种试验，对新品种进行了测试。在新墨西哥州，Acala 1517-21的产量类似于中型品种或转基因商业Acala品种，包括“ PHY 725 RF”，“ PHY 755 WRF”，“ PHY 764 WRF”，“ FM 2322GL”和“ FM 1830GLT”。与“ Acala 1517-08”相比，Acala 1517-21的平均棉绒产量高12.9％，棉绒百分比高11.5％，棉铃重，纤维长度，长度均匀性，伸长率，马克隆值和短纤维含量相似。但是，Acala 1517-21的纤维强度相似或略低，其中一项测试的强度和伸长率明显较低。与横跨棉带的商业转基因和非转基因品种相比，Acala 1517-21始终具有更长和更坚固的纤维或更低的马克隆值。Acala 1517-21是高产的陆地棉品种，皮棉百分比高，主食长。
