摘要

基因型与环境的交互作用包括个体基因型对不断变化的环境条件的不同反应。这一现象的重要性给育种工作带来了很大困难。一方面,育种者希望基因型稳定,即无论环境条件如何,产量都相似。另一方面,为每个地区选择最佳基因型是育种者和农民面临的主要挑战之一。本研究的目的是评估植物育种斯莫里斯有限公司(Plant Breeding Smolice Co.该研究利用加性主效应和乘性交互作用(AMMI)模型,对植物育种斯莫里斯有限公司开发的玉米杂交种的谷物产量进行了基因型与环境的交互作用评估。调查涉及 69 个玉米(Zea mays L.)杂交种,在五个地点进行了试验,采用随机完全区组设计,三次重复。谷物产量从 8.76 吨/公顷(斯莫利兹的 SMH_16417)到 16.89 吨/公顷(普瓦茨科沃的 SMH_16043)不等,平均产量为 13.16 吨/公顷。AMMI 分析表明,基因型、环境及其交互作用对谷物产量有显著影响。方差分析表明,在谷物产量的总变异中,环境因素占 25.12%,基因型差异占 35.20%,基因型与环境的交互作用占 21.18%。由于杂交种 SMH_1706 和 SMH_1707 具有较高的稳定性和优异的平均谷物产量,因此推荐用于进一步的育种计划。

Genotype-environment interaction for grain yield in maize (Zea mays L.) using the additive main effects and multiplicative interaction (AMMI) model.

Genotype-environment interaction consists of the different response of individual genotypes resulting from changing environmental conditions. Its significance is a phenomenon that makes the breeding process very difficult. On the one hand, the breeder expects stable genotypes, i.e., yielding similarly regardless of environmental conditions. On the other hand, selecting the best genotypes for each region is one of the key challenges for breeders and farmers. The aim of this study was to evaluate genotype-by-environment interaction for grain yield in new maize hybrids developed by Plant Breeding Smolice Co. Ltd., utilizing the additive main effects and multiplicative interaction (AMMI) model. The investigation involved 69 maize (Zea mays L.) hybrids, tested across five locations in a randomized complete block design with three replications. Grain yield varied from 8.76 t ha-1 (SMH_16417 in Smolice) to 16.89 t ha-1 (SMH_16043 in Płaczkowo), with a mean yield of 13.16 t ha-1. AMMI analysis identified significant effects of genotype, environment, and their interaction on grain yield. Analysis of variance indicated that 25.12% of the total variation in grain yield was due to environment factor, 35.20% to genotypic differences, and 21.18% to genotype by environmental interactions. Hybrids SMH_1706 and SMH_1707 are recommended for further breeding programs due to their high stability and superior average grain yield.
