中植372是中国农科院植保所,从抗虫棉与丰产棉品种复合杂交后代中选育出的新品系,具有抗棉铃虫、棉蚜、枯萎病、高产、优质等优点。 1、抗病虫性 1989年在中国农科院植保所试验田鉴定,中植372抗棉铃虫为Ⅰ级(高抗),抗棉蚜为Ⅲ级(中抗)。1991年在河北省东光县试验表现抗棉铃虫、棉蚜,兼抗枯萎病,高产。1992年该县扩大试种,在棉
Zhongzhi 372 is a new line selected from the progeny of the hybrid cross between insect-resistant cotton and high yielding cotton by Plant Protection Institute of Chinese Academy of Agricultural Sciences. It has the advantages of resistance to bollworm, cotton aphid, blight, high yield and high quality. 1, resistance to pests and diseases In 1989 in the Chinese Academy of Agricultural Sciences Institute of Plant Protection field identification, planting 372 resistance to bollworm Ⅰ level (high resistance), resistance to cotton aphid Ⅲ grade (resistance). In 1991, Dongguang County in Hebei Province showed resistance to bollworm, cotton aphid, wilt resistance and high yield. In 1992 the county expanded its trial planting in cotton

棉花是我国最重要的经济作物之一,也是主要的自然纤维作物。棉纤维是由胚珠外的单个表皮细胞分化发育而来的,棉纤维发育的各个时期中有多种不同的基因共同参与纤维形态的建成,因此发现和研究棉花纤维发育相关基因具有重要的理论价值与现实意义。本实验从新乡小吉无绒无絮(XinWX)和无绒有絮(XinFLM)纤维起始期竞争杂交的29K芯片上挑选了具有极显著性差异的三个基因GMOC、GhHPSE、GhGDSL,分别克
