“…Interaction may be positive in one principal component (PC) axis and negative in another. Same type of result had been observed by Bhakta (2005) and Suthamathi and Nallathambi (2016). The IPCA I scores of hybrids ranged from -3.91 (P3502) to 2.90 (ZH17206) and IPCA II scores ranged from -2.52 (ZH17210) to 3.29 (ZH17225).…”

Thirty maize hybrids were evaluated for stability of yield performance across six locations of Odisha using the additive main effect and multiplicative interaction (AMMI) model. The analysis of variance revealed significant difference among genotypes, environments, G x E interactions, IPCA I, IPCA II and IPCA III scores. Among the high yielding genotypes, ZH17210, ZH159, ZH17223, P3502 and ZH161418 recorded low interaction, 28(ZH159) and 2(ZH161418) exhibited positive interactions (both IPCA 1 and IPCA II had same sign) and 6(ZH17223) revealed negative interaction. Koraput location(E6) was found to be most favorable environment while Banjanagar (E2) indicated as a poor environmental condition for grain yield. Bhubaneswar location with IPCA I and IPCA II scores close to zero seems to have minimum environmental interaction for grain yield. Among the hybrids; ZH17229), VH151139 and ZH161418 showed higher grain yield and minimum interaction (IPCA I) and hence, may be considered most stable. In contrast, the highest yielding hybrid ZH17210 demonstrated differential yield performance over environment and appreciably higher magnitude of G x E interaction (IPCA I) indicating adaptation to specific environment.

“…The target of plant breeders will usually develop varieties with adaptability to a broad environment [17]. The yields are strongly influenced by the environment, which causes varying results, both in several years of planting in one location and in several locations even in different locations in several years of the growing season [18]. Other researchers found that progeny number 110 of oil palm was the most stable among the 6 progenies tested in three different locations [19].…”

A challenge still being faced at the coconut farmers’ level is the low productivity, which is only at an average of 1.2 tons of copra per hectare per year. Apart from being caused by old plant age, it is also caused by low-quality seeds. The types of superior coconut that are currently available are still limited, especially the tidal-specific varieties. The research was conducted in the Village of Tanjung Solok, East Tanjung Jabung Regency, Jambi Province, Indonesia, from 2015 to 2018, using an observational survey, which was aimed to find promising lines of coconut that suitable for the tidal areas. The observed characters include vegetative, generative, and fruit components. The analysis of the coefficient variance was carried out to determine the level of variance and production potential of the Zabak Tall coconut. Meanwhile, the yield stability was analyzed by observing the linearity of the production characters for three years. The results showed that the productivity of Zabak Tall is at about 3.09 tons of copra per hectare per year, which is stable for three years of observation and even tends to increase due to selection activities.
