“…Hence, it is mandatory to split the contribution of individual sorghum genotypes to create the total GEI effect. And similar research results have been reported for most crops under Ethiopian conditions as, for example, Muhe and Assefa (2011) for bread wheat [7], Gedif and Yigzaw (2014) for potato [8], Adugna et al (2011) for finger millet [9]. This calls for the use of another model that fits the proper evaluation of the tested genotypes, and several methods are used to analyse GEI [10,11,12].…”

Abstract. A multi-environment sorghum variety trial comprised of nine genotypes along with one standard check, "yeju", was carried out in the main cropping seasons of the period of 2006-2008. The objective of this research was to identify a stable and betteryielding sorghum variety under the conditions of the sorghum-growing area of North Shewa, Ethiopia. The experiment was arranged in randomized complete block design replicated three times within an experiment. AMMI analysis based on grain yield data revealed that genotypes ICSV 1112BF, 82 LPYT-2 # 5x81ESIP 46, and PGRC/E #222880 were superior to the standard check both in grain yield and stability, and hence these genotypes have been verified, and the genotype PGRC/E #222880 has been registered by the national variety-releasing technical and standing committee by the given name "Chare" for commercial production for the North Shewa sorghum-growing areas.

Abstract:Finger millet is one of the potential cereal crops that can contribute to the efforts of realization of food security in the Sub-Saharan Africa. However, scientific information available with regards to improving soil phosphorus supply and identification of P efficient varieties for the crops potential yield is limited. In order to investigate the effects of P levels on yield components and grain yield On-station field experiments were conducted in two sites of western Kenya during the long and short rain seasons of 2015. The experiment was laid out in a Randomized Complete Block Design in factorial arrangement with four levels of P (0, 12.5, 25 and 37.5 kg P 2 O 5 ha -1 and three finger millet varieties (U-15, P-224 and a local check-Ikhulule) and the treatments replicated three times. The increase of phosphorus levels significantly (P≤0.05) increased the grain yield over the control up to 25 kg P 2 O 5 ha -1 during the long rain seasons and 25 kg P 2 O 5 ha -1 during the short rain seasons in both sites. Interactions at P≤0.05 were revealed on the grain yield where improved variety P-224 at 25 kg P 2 O 5 ha -1 produced the highest grain yield of 4.74 t.ha -1 in Alupe and 4.77 t.ha -1 in Kakamega and the consistent results suggest that the combination is highly recommended. Therefore the use of judicious and proper rates of P fertilizers can markedly increase the grain yield of finger millet in western Kenya.

“…The second approach is to find stable genotypes and to use them across a range of environments (FINLAY and WILKINSON, 1963). However, stability per se is not necessarily a positive factor and it is desirable only when associated with high mean yield (ADUGNA et al, 2011). Present study evidenced that Hungarian provenance Valkonya (HU42) showed average stability over tested environments, as well as above average mean height growth.…”

Provenance by site interaction and stability analysis of European beech (Fagus sylvatica L.) provenances grown in common garden experiments

Fifteen provenances of European beech (Fagus sylvatica L.) were evaluated for stability and adaptability by height growth at four test sites in Bosnia and Herzegovina (1), Croatia (1) and Serbia (2). Provenance trials were established in spring 2007 by planting 2- and 3-yearold seedlings and arranged in a randomized complete block design. The data from seven 6- year-old and eight 5-year-old provenances were obtained in 2009 and analyzed separately. Finlay and Wilkinson’s regression analysis and Additive main effects and multiplicative interaction model (AMMI model) were used to assess provenance by site interaction (P × S) and to identify beech provenances that have high and stable performance in different environments, at the juvenile stage of development. Analysis of variance showed that effects of provenance, site, and P×S interaction are highly significant (p<0.001) in both age groups. Linear regression model evidenced that most of the provenances had regression coefficients not significantly different from unity (b=1.0), except for provenances Sjeverni Dilj Caglinski (HR24) and Vranica-Bistrica (BA59). The partitioning of the total sum of squares (SS) exhibited that the site effect was the predominant source of variation in both age groups of provenances (50.7% and 38.5%, respectively). Additionally, regression analysis explained 15.8% and 33.2% of provenance by site interaction terms, in provenances age six and five years, respectively, while the AMMI analysis accounted for 62.2% and 78.7% in P×S interaction. The results of AMMI showed that the first principal component (PC1) was statistically significant in both age groups. Adaptability and stability of provenances to the test sites were estimated with AMMI1 and AMMI2 biplots. Provenance Sjeverni Dilj Caglinski (HR24) showed constant performance over tested sites, characterizing with aboveaverage height growth at low yielding environments. Provenances HR25 and BA61 showed the opposite type of adaptation, being adapted to high yielding sites. Provenance Valkonya (HU42) was characterized by IPCA1 score close to zero and above average mean height growth, suggesting general adaptation to the tested environments. The implication of P×S was discussed in light of impact of climate change on beech and selection of most suitable provenances for future reforestation programs.
