‘UA212ne’ (Reg. no. CV‐143, PI 692970) is a conventional, nectariless cotton (Gossypium hirsutum L.) cultivar released by the Arkansas Agricultural Experiment Station in September 2018. The cultivar represents an ongoing effort to develop improved genotypes having enhanced yield, yield components, earliness, host plant resistance, and fiber properties. The nectariless trait effectively reduces population densities of tarnished plant bug, the major insect pest in Arkansas cotton. UA212ne was compared with ‘DP 393’ and ‘UA48’ for 4 yr at four test sites in Arkansas. Across all test sites, lint yields of UA212ne was 8.4 and 13.6% higher than those of DP 393 and UA48, respectively, with higher relative yields on silt loam soils than on clay soils. In the 2016 Regional Breeders’ Network Test, UA212ne produced lint yields equal to the highest yielding line at each location. Yields of UA212ne were produced with highly efficient yield components, namely very high values of lint percentage, lint index, fibers per seed, and fiber density. Host plant resistance traits that have been measured on UA212ne include bacterial blight resistance, Verticillium wilt tolerance, and resistance to tarnished plant bug. This combination of host plant resistance and yield components should lead to more stable yield production across contrasting environments. Fiber quality of UA212ne exceeded that of DP 393 but was lower than UA48 and was similar to that of ‘UA222’.

无油棉棉花品种“ UA212ne”的注册

'UA212ne'（Reg。no。CV-143，PI 692970）是一种传统的无油棉（陆地棉）L.）品种于2018年9月由阿肯色州农业实验站发布。该品种代表着不断的努力，旨在开发具有增强的产量，产量构成，早熟性，寄主植物抗性和纤维特性的改良基因型。无油烟性状有效地降低了失去光泽的臭虫的种群密度，这种臭虫是阿肯色州棉花的主要害虫。在阿肯色州的四个测试点将UA212ne与“ DP 393”和“ UA48”进行了4年的比较。在所有试验点上，UA212ne的皮棉产量分别比DP 393和UA48高8.4和13.6％，粉质壤土的相对产量高于黏土。在2016年区域饲养员网络测试中，UA212ne产生的皮棉产量等于每个地点的最高产量系。UA212ne的产量是由高效的产量构成因素产生的，即非常高的皮棉百分比，皮棉指数，每粒种子纤维和纤维密度值。在UA212ne上测得的宿主植物抗性特征包括细菌性白叶枯病抗性，黄萎病耐性和对失去光泽的植物虫的抗性。宿主植物抗性和产量构成要素的这种结合应可在不同的环境下实现更稳定的产量生产。UA212ne的纤维质量超过DP 393，但低于UA48，与'UA222'相似。宿主植物抗性和产量构成要素的这种结合应可在不同的环境下实现更稳定的产量生产。UA212ne的纤维质量超过DP 393，但低于UA48，与'UA222'相似。宿主植物抗性和产量构成要素的这种结合应可在不同的环境下实现更稳定的产量生产。UA212ne的纤维质量超过DP 393，但低于UA48，与'UA222'相似。
