为了通过研究不同长相穗型小麦穗部特性,以达到提高产量和挖掘穗部潜力的目的。本文对长方型、棍棒型、椭圆型和纺锤型四种不同长相穗型小麦品种的穗部性状特性进行了分析。结果表明不同穗型小麦在小花数、穗粒数、粒重等方面均表现出先升后降的二次曲线趋势,但不同穗型小麦表现趋势不同,长方型和椭圆型小麦在穗粒数、穗重、各粒位粒重等方面均优于棍棒型和纺锤型小麦,棍棒型小麦由于其特殊的穗型结构,在小穗密度、粒重等方面表现独特,纺锤型小麦在各方面表现均较差。结果表明,在小麦生产用种和品种选育上,穗型的选择至关重要。长方型小麦有提高小麦产量的潜力。
In order to study the characteristics of panicles with different shape and length of panicle, we can achieve the goal of increasing yield and ear potential. In this paper, the panicle traits of four wheat cultivars with rectangular shape, stick shape, oval shape and spindle shape were analyzed. The results showed that the trend of the quadratic curve of different types of spikes increased first and then declined, but the trend of different types of spikes was different. The average number of spikelets per spike , Spike weight and grain weight of each grain were better than that of clubs and spindle wheat. Because of its special ear type structure, club wheat was unique in spikelet density and grain weight. Spindle wheat in all aspects Poor performance. The results showed that the selection of panicle type is very important in the selection of wheat varieties and varieties. Barley has the potential to increase wheat yield.
