中文摘要:
      于2018—2019年在山东省泰安市马庄试验田采用随机区组设计,包含品种、灌溉两因素,选用14个小麦新品种(系),水分处理分别为出苗后不浇水(E1)、浇拔节水(E2)和浇拔节+开花水(E3),3次重复,共126个小区。分别考察不同处理的小区产量、株高、单穗粒重、单穗穗粒数、单穗小穗数、单穗不孕小穗数等6个性状的变化情况,应用方差分析法和R语言的GGE双标图方法分析性状的基因型效应、环境效应、基因型与环境的互作效应。结果表明,节水型小麦新品系均存在基因型效应(G)、环境效应(E)和基因型×环境互作效应(GE)且均表现出极显著差异(P<0.05),基因型效应(G)的变异范围为1.07%~60.17%,环境效应(E)的变异范围为14.42%~86.97%,基因型×环境互作效应(GE)的变异范围为4.33%~47.88%。不同品种(系)的群体产量性状和个体农艺性状在不同环境下的适应性不同,表现为在不同灌水条件下,不同品种(系)处于不同多边形的顶角位置不同;小麦新品种(系)不同个体性状在不同浇水环境下表达程度不同。E1环境有利于单穗不孕小穗数的表达,E2有利于单穗粒重的表达,E3有利于株高的表达;不同环境对群体产量性状和个体农艺性状的鉴别力和代表性不同,E1环境比E2、E3环境具有更好的鉴别力和代表性。综上,在黄淮麦区,本研究所选用的14个节水型小麦新品种(系)农艺性状基因型效应及其与环境互作效应差异显著,E1环境有利于小麦节水新品种(系)群体产量和个体农艺性状的选择。
英文摘要:
      From 2018 to 2019, a random block design was used in the Mazhuang experimental field, Tai’an City, Shandong Province. The experiment included two factors:14 new wheat varieties (lines) and 3 different irrigation conditions. The irrigation treatments consisted of no watering after emergence (E1), jointing water (E2), and jointing + flowering water (E3),repeating 3 times for each wheat variety (line) and ending up with a total of 126 plots. The changes of 6 traits including yield, plant height, grain weight per spike, number of grains per spike, number of spikelets per spike, and infertile spikelets per spike under different treatments were investigated respectively.The genotype effect, environment effect, and interaction effect of genotype and environment were analyzed by ANOVA and GGE biplot method of R language. The results showed that there were genotype effects (G), environmental effects (E) and genotype × environment interaction effects (GE) in the new water\|saving wheat lines, all having extremely significant differences (P<0.05). The variation range of G was 1.07%~60.17%, the variation range of environmental effect (E) was 14.42%~86.97%, and the variation range of genotype × environmental interaction effect (GE) was 4.33%~47.88%.The adaptability of population yield traits and individual agronomic traits of different varieties (lines) to different environments was different, meaning that under different irrigation conditions, different varieties (lines) were in different vertex positions of different polygons. Different individual traits of new wheat varieties (lines) were expressed differently in different watering environments. E1 was favorable for the expression of infertile spikelets per spike, E2 was favorable for the expression of grain weight per spike, and E3 was favorable for the expression of plant height. E1 was more discriminative and representative than E2 and E3. To sum up, in the Huanghuai wheat area, the 14 new water\|saving wheat varieties (lines) selected in this study had significant differences in the genotype effects of agronomic traits and their interaction effects with the environment. E1 was beneficial to the new water\|saving wheat varieties (lines) selection of population yield and individual agronomic traits.
