The New Mexico Agricultural Experiment Station announces the release of a glandless ‘NuMex COT 17 GLS’ cotton (Gossypium hirsutum L.) (Reg. no. CV‐141, PI 691837), which carries the incomplete dominant glandless allele Gl₂^e. NuMex COT 17 GLS was derived from an advanced backcross progeny of a cross between the Gl₂^e allele donor ‘Bahtim 110’ (G. barbadense L.) and glanded upland cotton ‘CRI 12’, followed by five backcrosses with glanded upland ‘CRI 35’ as the recurrent parent. It is resistant to Fusarium wilt (FW) race 4, with a level of resistance similar to the resistant checks ‘PHY 802RF’ and ‘PHY 811RF’, when evaluated in two naturally infected fields in California, and it is more resistant than ‘Acala 1517‐08’ when evaluated in the greenhouse in New Mexico. This new cultivar was tested in seven replicated field trials in New Mexico in 2013–2017 and in 11 tests across nine states in 2014. Compared with glandless ‘Acala GLS’, ‘Acala 1517‐18 GLS’, and ‘NuMex COT 15 GLS’, NuMex COT 17 GLS yielded 26, 16, and 13% more lint, respectively, and produced 93% of glanded Acala 1517‐08 yield. It had significantly higher lint percentage than all the check cultivars. It is classified as a medium staple with fiber quality inferior to long‐staple Acala cotton cultivars. NuMex COT 17 GLS is especially adapted to the Mississippi Delta and was the top yielder in the region. It is resistant to four races of bacterial blight and less susceptible to Alternaria leaf spot than Acala 1517‐08. The release of NuMex COT 17 GLS represents one of the first successful introgressions from G. barbadense germplasm with FW race 4 resistance.

带有枯萎病4号抗性的无腺'NuMex COT 17 GLS'陆地棉品种的注册

新墨西哥州农业实验站宣布发布无腺'NuMex COT 17 GLS'棉花（陆地棉）（Reg。no。CV-141，PI 691837），其携带不完整的显性无腺等位基因Gl ₂ ^e。NuMex COT 17 GLS从之间的交叉的一种先进的回交后代衍生的胃肠₂ ^ë等位基因的供体“Bahtim 110”（海岛棉L.）和陆地棉“ CRI 12”，然后进行5次回交，以陆地棉“ CRI 35”作为轮回亲本。在加利福尼亚州的两个自然感染田间进行评估时，它对枯萎病（FW）第4种族具有抗性，其抗性水平与抗性检查“ PHY 802RF”和“ PHY 811RF”相似，并且比“ Acala”更具抗性在新墨西哥州的温室中评估时为1517-08'。该新品种于2013–2017年在新墨西哥州进行了七次重复田间试验，并于2014年在九个州进行了11次试验。与无填料的“ Acala GLS”，“ Acala 1517-18 18 GLS”和“ NuMex COT 15 GLS”进行了比较。 ，NuMex COT 17 GLS分别增加了26％，16％和13％的皮棉，并产生了93％的Acala 1517-08产量。它的皮棉百分比显着高于所有检查品种。它被分类为中等品质的短纤维，其纤维品质不如长绒头Acala棉花品种。NuMex COT 17 GLS特别适合密西西比三角洲，是该地区产量最高的地区。与Acala 1517‐08相比，它对四种细菌白叶枯病具有抵抗力，并且对链霉病叶斑病的敏感性较低。NuMex COT 17 GLS的发布代表了来自G. barbadense种质具有FW第4种抗性。
