“…A study on stability analysis for nine genotypes of Elite Irish Potato (Solanum tuberosum L.) was con ducted in western Ethiopia. The study r evealed CIP384321.30 as the stable genotype for the region on the basis of the mean tuber yield, regression slope identified, and GGE biplot (Fufa and Fufa, 2021). Similar conclusions were drawn from our present study in which stable germplasm was identified across the studied environments along with individual stable germplasm f o r e a c h e n v i r o n m e n t w i t h t h e w h i c h -w o n -w h e r e pattern approach.…”

Solanum khasianum is a medicinally important plant that is a source of steroidal alkaloids ‘solasodine.’ It has various industrial applications, including oral contraceptives and other pharmaceutical uses. The present study was based on 186 germplasm of S. khasianum, which were analyzed for the stability of economically important traits like solasodine content and fruit yield. The collected germplasm was planted during Kharif 2018, 2019, and 2020 in RCBD with three replications at the experimental farm of CSIR-NEIST, Jorhat, Assam, India. A multivariate approach for stability analysis was applied to identify stable germplasm of S. khasianum for economically important traits. The germplasm was analyzed for additive main effects and multiplicative interaction (AMMI), GGE biplot, multi-trait stability index, and Shukla’s variance which were evaluated for three environments. The AMMI ANOVA revealed significant GE interaction for all the studied traits. The stable and high-yielding germplasm was identified from the AMMI biplot, GGE biplot, Shukla’s variance value, and MTSI plot analysis. Lines no. 90, 85, 70, 107, and 62 were identified as highly stable fruit yielders while, lines no. 1, 146, and 68 were identified as stable high solasodine lines. However, considering both traits, i.e., high fruit yield and solasodine content, MTSI analysis was performed which showed that lines 1, 85, 70,155, 71, 114, 65, 86, 62, 116, 32, and 182 could be used in a breeding program. Thus, this identified germplasm can be considered for further varietal development and could be used in a breeding program. The findings of the present study would be beneficial for the S. khasianum breeding program.

“…Any cultivars with a significant  2  are regarded as unstable. This stability analysis on potato has been used for interpreting results of multi-environment trials and selecting superior breeding clones and suitable cultivars, for example, in Brazil (Souza Lambert et al 2006), Canada (Tai and Young 1972), Ethiopia (Fufa and Fufa 2021), India (Raja et al 2018), Iran (Hassanpanah et al 2008), Kenya (Lung'Aho et al 1998, Naawe 2020, Latvia (Skrabule et al 2015), Perú (Ortiz et al 1991), Türkiye (Pehluvan et al 2006, Uganda (Kakuhenzire et al 2004) and USA (Mackenzie et al 1976, Darmo andPeloquin 1990); while the CV facilitated identifying promising potato bred-germplasm in Iran under water deficit and potassium humate (Hassanpanah et al 2008), or in Kenya (Naawe 2020) and in Poland (Przystalski and Lenartowicz 2020).…”

“…Likewise, the AMMI modeling facilitates delineating mega-environments and improves trial accuracy. AMMI has been used for analyzing multi-environment potato yield trials in Brazil (Queiroz de Souza 2007), Croatia (Mijić et al 2019), Ethiopia (Worku et al 2018, Fufa andFufa 2021), Iran Azimi 2010, Mohammadnia et al 2021), Kenya (Naawe 2020), Korea (Kim et al 2017), Rwanda (Placide et al 2022, and Uganda (Mulema et al 2008). Its modeling, particularly when using the ensuing biplots, led to identifying breeding clones for further cultivar registration and suitable cultivar for respective sites in the target population of environments.…”

The aim of potato breeding is to release cultivars showing high and stable performance across the target population of environments. The objective of this research was therefore to investigate the use of various methods (site-regression [SREG], coefficient of variation and the regression’s deviations [σ2δ]) for determining adaptability and stability for productive and quality traits in the Nordic Region of Europe. The multi-environment trials included 256 breeding clones and released cultivars grown by EU farmers at three distinct testing sites over two years in Sweden. There was significant (P < 0.001) variation for tuber yield, starch percentage and reducing sugars in the tuber flesh among breeding clones and cultivars, testing environments and their GEI. The environments were very diverse as revealed by SREG biplots and particularly for the GEI patterns noted in productive and quality characteristics. The percentage of stable high-tuber yielding germplasm was larger for breeding clones (23%) than for the European released cultivars (2%), thus showing the advantage of potato breeding in the target population of environments. SLU 1415001 and SLU 1314015 were the most promising breeding clones due to their stable high tuber yield. The starch potato cultivars were the best for this characteristic, although none of them had a non-significant σ2δ. ‘Talent’ shows an almost stable good performance among low reducing sugar cultivars and breeding clones, which were often unstable in their scoring across environments. Neither a breeding clone nor a cultivar was at the top ranking for stable tuber yield, tuber flesh starch and reducing sugars in the tuber flesh, which shows the challenge faced by potato breeding while addressing the need of different markets.
