“…Hence, the breeding of genotypes having a diverse genetic base is essential to achieve a desirable level of self-sufficiency and sustainability. According to Ashraf et al (2001) the adaptability of a variety over diverse environments is usually indicated by the degree of its interaction with the different environments in which it is grown. A variety or genotype is considered to be more adaptive or stable if it has a high mean yield but a low degree of fluctuation in its yield when grown over diverse environments (Ashraf et al, 2001).…”

This research was conducted in three different locations of, Turkey, during the 2005-2006 and 2006-2007 growing seasons. In this study, eight triticale genotypes were used as trial material. The triticale genotypes C9, C11, Nx2015(17) and Nx2003(12), based on high grain yield and high stability, were identified as promising genotypes for the region. In particular, genotypes C9 and Nx2003(12) were considered to be stable genotypes, in terms of grain yield, for the southern Marmara region of Turkey because of their minimal Sdi2 and bi values near 1. In addition, genotype Nx2003(12) had a higher grain yield than the general mean. Accordingly, this genotype is recommended as having especially good adaptability in all environments.

“…The G × E interaction in various crops was studied by different research workers (Ashraf et al, 2001; Zubair and Ghafoor, 2001). For measuring phenotypic stability in grain legumes, stability parameters have also been studied (Bakhsh et al, 1995; Sharif et al, 1998, Qureshi, 2001).…”

Core Ideas Genotype × environment interaction among 11 genotypes was highly significant over three different locations. Genotype NL 96475A was most stable for all environments. Genotype NL 96680 was suitable for low‐performing environments. The assessment and measurement of yield stability of a genotype over environments is an important component of a certain breeding program. Ten elite genotypes of lentil (Lens culinaris Medik) and one check variety were evaluated for their adaptability at three different locations of Punjab Province, viz—Nuclear Institute for Agriculture and Biology (NIAB), Faisalabad; Barani Agricultural Research Institute (BARI), Chakwal; and Arid Zone Research Institute (AZRI), Bhakar. Trials were conducted during two consecutive years (2013–2014). Genotype × environment interactions (of crossover nature) among 11 genotypes and 3 environments were observed to be highly significant. Mean seed yield was found maximum for NL 56‐1 (718 kg ha−1) followed by NL 96475A (709 kg ha−1) during 2013. However, NL 96475A had shown stable performance at different locations and was better responsive to favorable conditions having high regression coefficients. NL 96680 also appeared to be a stable genotype for low‐performing environments, as it had a regression coefficient less than unity. In the year 2014, the same genotypes, NL 96475A and NL 96680, had shown stable performance. NL 96475A was found suitable for all environments, and NL 96680 was suited to a low‐performing environment. On the basis of these observations, it has been concluded that NL 96475A was the most stable genotype with mean yield greater than the grand mean, nonsignificant estimates of unit regression coefficient, and deviation from regression.

“…The adaptability of a variety over a diverse environment is usually tested by the degree of its interaction with it (Ashraf et al, 2001). The importance of genotype × environment (G×E) interactions in breeding programs has been demonstrated in many major crops, including wheat (Najafian et al, 2010;Zali et al, 2011).…”

The research is financed by Swedish Research Council (Vetenskapsradet) U-Forsk2013, "Deployment of molecular durum breeding to the Senegal Basin: capacity building to face global warming". AbstractThe Senegal River basin (Guinea, Mali, Mauritania, and Senegal) is a key agricultural production area in sub-Saharan Africa. Here, rice fields are left fallow during the cooler winter season, when the night temperatures reach 16 °C but the maximum daily temperatures remain above 30 °C. This season was used for the first time to conduct multi-environmental trials of durum wheat. Twenty-four elite breeding lines and cultivars were tested for adaptation during seasons 2014-15 and 2015-16 at two stations: Kaedi, Mauritania and Fanaye, Senegal. Phenological traits, grain yield and its components were recorded. Top grain yield was recorded at 5,330 kg ha -1 and the average yield at 2,484 kg ha -1 . The season lasted just 90 days from sowing to harvest. Dissection of the yield in its components revealed that biomass and spike fertility (i.e. number of seeds produced per spike) were the most critical traits for adaptation to these warm conditions. This second trait was confirmed in a validation experiment conducted in 2016-17 at the same two sites. Genotype × environment interaction was dissected by AMMI model, and the derived IPC values used to derive an 'AMMI wide adaptation index' (AWAI) to asses yield stability. The use of a selection index that combined adjusted means of yield and AWAI identified three genotypes as the most stable and high yielding: 'Bani Suef 5', 'DAWRyT118', and 'DAWRyT123'. The last two genotypes were also confirmed among the best in a validation trial conducted in season 2016-17. The data presented here are meant to introduce to the breeding community the use of these two research stations along the Senegal River for assessing heat tolerance of wheat or other winter cereals, as well as presenting two new ideal germplasm sources for heat tolerance, and the identification of spike fertility as the key trait controlling adaptation to heat stress.
