该文利用1980～1992年全国黄推南片及河南省水地小麦区试资料，分析了“六五”和“七五”黄推南片麦区育成品种特点及在生产上的应用情况，根据该区的生态条件、生产发展水平等一系列综合条件，提出大面积（亩产350～450公斤）生产条件下对丰产稳产广泛适应性品种性状的要求和今后的有种目标．并在选育广泛适应性品种的方法和途径上，与育种者商榷。黄淮南片麦区是全国的第一大产麦区，孩区横跨豫（中北）、皖（北）、苏（北）、陕（关中）四省，生态、土壤、气侯等条件复杂，对小麦品种的要求比较严格。1980年以来，该区各育种单位开展了联合攻关，培育出很多小麦新品种，！980～1992年仅黄淮南片冬、春水两组区试就鉴定了96个品种，其中有25个经国家或豫、皖、苏、陕等省审定，在生产上广泛应用，对该区小麦单产和总产的不断提高起到了积极推动作用。因此，了解核区小麦品种选育和利用特点及大面积生态环境对小麦品种的要求，将有助于确定今后育种目标和选育模式，培育出适于该区大面积广泛利用的突破性品种。
Based on the data of Huangtuonan films from 1980 to 1992 and wheat-water samples from Henan Province, the characteristics and the application of Huangtuonan films in the “Sixth Five-Year” and “Seven-Year-Five” Ecological conditions, production and development level of a series of comprehensive conditions, proposed a large area (mu to produce 350 ~ 450 kg) under the conditions of production of a wide range of adaptability to high yield stable varieties traits and future objectives. And in breeding a wide range of adaptive methods and ways to discuss with the breeders. Huanghuainan South Area is the largest grain-producing area in China. The area extends across the four provinces of Yu (North), Su (North) and Shaanxi (Guanzhong) areas, including ecology, soil and climate Complex, more stringent requirements of wheat varieties. Since 1980, various breeding units in the area have conducted joint research to breed many new wheat varieties! From 1980 to 1992, only 96 samples of Huanghuangnan slice were identified in the winter and spring seasons. Among them, 25 were identified by the state or Henan, Anhui, Jiangsu and Shaanxi provinces, and were widely used in production. The continuous improvement of yields and gross production has played a positive role in promoting. Therefore, to understand the characteristics of breeding and utilization of wheat varieties in the nuclear region and the requirements of large-scale ecological environment on wheat varieties will help to determine future breeding objectives and breeding patterns and to breed groundbreaking varieties suitable for extensive use in this area .
