Abstract

Twenty Black Cumin genotypes were evaluated across locations to assess their agronomic performance, genotype by environment interaction and seed yield stability during 2011 and 2012 at Sinana, Goro and Ginir in randomized complete design with three replications. Except the number of capsules per plant, the analysis of variance indicated that there was highly significant variation (p<0.01) among the genotypes in days to flower, plant height, primary branches, days to maturity, biomass yield and seed yield. The combined analysis of variance indicated that the genotype x environment interaction was highly significant (p<0.01) indicating that there is a need to know which component of the interaction is contributing to the variation. The genotype by environment interaction explained contributed to the majority (79.16%) of the variation while the genotype and environment respectively explained 19.72 and 1.12% of the total sum of squares. The variation is majorly contributed by the genotype x environment interaction than genotype indicating that there was substantial difference in genotypic response across environments. AMMI stability analysis revealed that all the four AMMI components are highly significant. The first and second principal components contributed 70.85% and 17.0% of interaction sum of squares respectively. The PCA1 and PCA2 had sum of squares greater than that of genotypes and cumulatively contributed to 87.86% of the total GEI. Based on the calculated AMMI stability value, BC-DM-9 was the most stable genotypes followed by ACBC- 6 and AC-BC-19. On the other hand, genotype AC-BC-10 was the most unstable followed by MAB-057, ACBC- 8, Local and AC-BC-4. AMMI biplot of seed yield indicated that BC-DM-11 Xereta-1, AC-BC-9 and MAB-018 expressed a highly interactive behavior while genotype 394640-539 showed low interaction and thus stable in its seed yield (kg/ha).
埃塞俄比亚东南部贝尔种植黑孜然基因型的农艺性能、X基因型环境相互作用及稳定性
采用3个重复的随机完全设计,对2011年和2012年Sinana、Goro和Ginir地区的20个黑孜然基因型进行了农艺性能、环境互作基因型和种子产量稳定性评估。除单株蒴果数外,各基因型在开花天数、株高、一次枝、成熟期、生物量产量和种子产量上均存在极显著差异(p<0.01)。综合方差分析表明,基因型与环境相互作用极显著(p<0.01),表明有必要了解相互作用的哪一部分导致了变异。受环境互作影响的基因型占变异总平方和的大部分(79.16%),基因型和环境分别占变异总平方和的19.72%和1.12%。这种变异主要是由基因型与环境的相互作用造成的,而不是由基因型造成的,这表明不同环境下的基因型反应存在实质性差异。AMMI稳定性分析表明,四种AMMI成分均高度显著。第一主成分和第二主成分对交互作用平方和的贡献率分别为70.85%和17.0%。PCA1和PCA2基因型的平方和大于基因型的平方和,累计贡献了总GEI的87.86%。根据AMMI稳定性值计算,BC-DM-9是最稳定的基因型,其次是ACBC- 6和AC-BC-19。AC-BC-10基因型最不稳定,其次是MAB-057、ACBC- 8、Local和AC-BC-4。种子产量AMMI双图显示BC-DM-11 Xereta-1、AC-BC-9和MAB-018表现出高度互作行为,而基因型394640-539表现出低互作行为,因此其种子产量(kg/ha)稳定。
