在新的社会主义建议七年计划中棉花产量问题,特别是颇有价值的细绒棉品种,具有特别的重要性,并要寻求新的方法使在提高产量上产生最大的效果。正如多年试验的证明,要培育选育的棉花品种,除了运用先进的农业技术措施——正方形穴播的植株配置和二个方向的机械化耕作外,应当认定在实践中引用以结合极优良的纤维品质而高产的第一代杂种的种间杂种优势是重要措施之一。在植棉业上研究杂种优势现象和杂种种子的工

The issue of cotton production, especially the valuable cashmere varieties, is of particular importance in the new Socialist proposal for a seven-year plan and is looking for new ways to make the most impact in increasing yields. As many years of experiments have proved, in order to breed cotton varieties for breeding, in addition to the use of advanced agricultural technology measures - planting of plants by square hole sowing and mechanized farming in two directions, reference should be made in practice to incorporate very good fiber quality The interspecific heterosis of high-yielding first-generation hybrids is one of the important measures. Workers who study the phenomenon of heterosis and hybrid seeds in the cotton industry
