目前在冀中南地区种植的小麦品种中,还有亩产八、九百斤的潜力。从产量构成因素的每亩穗数、每穗粒数和千粒重分析,通过提高穗粒数和千粒重有可能提高品种的丰产潜力,但这是一个粗略的认识,要确切了解产量构成因素间的相互关系,需要进行相关和通径分析,为选育高产类型的小麦新品种提供理论依据。 Currently in the wheat varieties planted in southern central China, there is the potential of 8,900 pounds per mu. From the analysis of yield components per acre panicle, grain number per spike and 1000-grain weight, it is possible to increase the yield potential of varieties by increasing the number of grains per spike and 1000-grain weight. However, this is a rough idea to understand exactly the relationship between yield components Relationship, the need for correlation and path analysis, to provide a theoretical basis for breeding high-yielding varieties of wheat varieties.
