摘要
高产是棉花育种的主要目标,目前我国棉花育种已达较高水平,本文提出了棉花高产育种的技术途径,(1)征集并研究利用多样化的种质资源;(2)产量结构要素的同步改良;(3)高生物学产量和高收获指数育种;(4)杂种优势利用。同时本文还从产量与竞争力相互关系出发,对改进棉花育种田间试验和选择方法提出了一些初步设想。
Cotton breeding was objected to increasing lint yield mainly. At present,greatimprovement has been obtained in high cotton breeding in China. In the paper,techniquesof high cotton breeding were pointed out(1)collection and utilization of diverse cottongermplasm;(2)coordinative improvement of yield subtraits;(3)breeding for high biologi-cal yield and high harvest index;(4)utilization of cotton heterosis;And from the relation-ship between yield and competition,primary thoughts were suggested to improve field testaid selection method of cotton breeding.
