小麦高产必须创造相应的生态类型。例如亩产1200斤,特别是1500斤以上的品种,其生态型必须能充分利用光能,提高光合效率。这样必须选育大穗类型,在此基础上考虑多穗。通过大穗、小叶、中秆来达到穗大、穗多、粒大的统一,才能突破高产关。高产生态型的探讨是小麦育种的核心问题之一。本文根据试验和观察材料对小麦高产生态型指标,提出一些初步论点,作为讨论的参考。一、巨型大穗:根据目前收集的小麦材料分析,高秆类型每亩穗数30-40万,如阿勃、184、毛阿夫、尤皮8号、丰产3号等;中秆类型每亩穗数46-60万,如矮丰3号、密穗
The high yield of wheat must create the corresponding ecological type. For example, 1200 kg per mu, especially more than 1500 pounds of varieties, their ecological type must be able to make full use of light, improve photosynthetic efficiency. This must breed big ear type, on this basis, consider more spike. Through the big spike, leaflets, stems to achieve spike large, spike, grain uniform, in order to break the high yield. The discussion of high yield ecotypes is one of the core issues in wheat breeding. Based on the experimental and observed materials on wheat ecotype index, put forward some preliminary arguments, as a reference for discussion. First, the giant big spike: According to the analysis of the current collection of wheat material, high-stalk type per acre 30-40 million, such as Aibo, 184, Mao Aifu, Youpi 8, such as high yield 3; Acre 46-60 million acres, such as Aifeng 3, dense spike
