摘要:

为了探究谷子品种的区域适应性,为谷子新品种培育提供参考,以‘豫谷18’、‘豫谷31’、‘豫谷32’、‘豫谷35’、‘豫谷38’、‘豫谷42’为试材,依据全国谷子品种区域适应性联合鉴定试验调查结果,运用变异系数、高稳系数、回归系数、光温相对敏感度等多种分析方法,对6个品种进行适应性及光温敏感分析。对各品种不同区组内的农艺性状进行统计分析,同时比较了区组间各品种不同性状的变异系数。结果表明6个谷子品种均能适应2个及以上的不同生态区组,尤其是‘豫谷18’在4个不同的生态区组均表现出高产、稳产和广适的特性;6个品种生育期在西北春谷早熟区组均较长,单穗重、单穗粒重和千粒重在西北春谷早熟区组、西北春谷中晚熟区组较高,穗长在东北春谷区组较长,产量及株高和出谷率没有明显的趋势;区组间各品种农艺性状的变异系数均是千粒重最小,抽穗期最大;以夏谷区为参照,‘豫谷18’单穗重、单穗粒重敏感度在不同区组均为最弱。‘豫谷18’在4个不同的生态区组均表现出高产、稳产和广适的特性。

Abstract:

In order to explore the regional adaptability of millet varieties and provide reference for the breeding of new millet varieties, ‘Yugu 18’, ‘Yugu 31’, ‘Yugu 32’, ‘Yugu 35’, ‘Yugu 38’ and ‘Yugu 42’ were selected as test materials. The adaptability and sensitivity to light and temperature of 6 varieties were analyzed by coefficient of variation, coefficient of high stability, regression coefficient and relative sensitivity to light and temperature.The agronomic characters of different varieties in different districts were analyzed statistically, and the variation coefficients of different characters among different districts were compared. The results showed that all 6 millet varieties could adapt to 2 or more different ecological regions, especially‘Yugu 18’ showed high yield, stable yield and wide adaptability in 4 different ecological regions. The growth period of the 6 varieties was longer in the early maturing group of northwest spring millet area, the panicle weight, grain weight per panicle and 1000-grain weight were higher in the early maturing group of northwest spring millet area and the middle and late maturing groups of northwest spring millet area, and the panicle length was longer in the northeast spring millet area. There was no obvious trend in yield, plant height and grain emergence rate. The coefficient of variation of agronomic traits was the smallest with 1000-grain weight and the largest at heading stage. Taking Xiagu district as reference, the sensitivity of ‘Yugu 18’ was the weakest in different district groups. ‘Yugu 18’ showed the characteristics of high yield, stable yield and wide adaptability in 4 different ecological regions.
