Stability analysis of BC2 abaca (Musa textilis Nee) hybrids across different locations in the Philippines
2020
Parducho, M.A.L. | Rama, R.A.B. | Lalusin, A.G.
Performances of the three abaca genotypes were evaluated in seven locations in the Philippines. Yield stability was determined using both parametric and non-parametric method and GGE biplot. BC2-7 had the best performance with regard to growth-related agronomic characters. CTRL outperformed the hybrids in terms of prolificacy though this could be attributed to sudden shift of growth from vegetative to reproductive stage due to stresses. Moreover, CTRL had the best fiber yield and fiber recovery among the three due to high tensile strength of pure abaca compared to the two hybrids. In addition, extreme values observed in control in some environments affected the overall result for yield-related characters. Eberhart and Russell's stability measures identified BC2-2 as the more stable genotype and revealed that hybrids could perform better than CTRL under less favorable environment. Kang, and Nassar and Huehn's stability measures identified BC2-7 as the most stable genotype. GGE biplots provided potential mega-environments for each genotype and ranking of environment showed the best growing location for abaca. Aside from these, biplots also showed that BC2-7 is the most stable genotype.
