Stability of oil palm (Elaeis guineensis Jacq.) progenies on yield and yield Components across environments using AMMI analysis

Abstract

Southern Thailand is annually affected by climate change, which impacts on yield performance of oil palm. Therefore, effect of climate change on adaptability, cultivation and yield of oil palm in various planting areas was investigated. This research aimed to evaluate the adaptability of six oil palm progenies (cross numbers 110, 118, 119, 130, 132 and 137) at 5 year-old-plants grown in three environmental areas of southern Thailand: Nakhon Si Thammarat, Phatthalung and Songkhla provinces. The experiment was arranged in a completely randomized design with five replications per treatment (1 tree/replicate) in each environment during 2013-2014. The additive main effects and multiplicative interaction (AMMI) model was used to analyze the stability of yield and yield components. The results showed that the variances attributed to environment (E), genotype (G) and their interactions (G x E) were highly significant. The yield of each progeny depended on growth location. The AMMI biplot analysis showed that progeny 110 was the most stable genotype based on yield and yield components in all the environments. The highest yield of fresh fruit bunches in Phatthalung, Songkhla and Nakhon Si Thammarat provinces were obtained in progeny 130 (403.16 kg/palm/year), progenies 132 and 137 (303.20 and 297.96 kg/palm/year), and progeny 119 (283.52 kg/palm/year), respectively. This indicates that the suitability of an oil palm progeny in general depends on the specific environment for planting.

Interacción genotipo x ambiente en Elaeis guineensis e Híbridos OxG de palma de aceite en Colombia

“…Okoye et al, (2008) obtuvieron diferencias significativas (p < 0,001) en el genotipo y el periodo de evaluación, para las variables rendimiento de RFF, número de racimos y peso promedio del racimo, en 15 genotipos (Deli x Ténera) evaluados en Nigeria durante 1999-2002. Bueraheng et al, (2018) observaron que las varianzas atribuidas al ambiente, el genotipo y a la interacción GxA, fueron significativas (p < 0,001) para seis progenies E. guineensis Ténera evaluadas en varias localidades del sur de Tailandia, con respecto a la estabilidad del rendimiento de aceite y sus componentes. Según los autores, el rendimiento de cada progenie evaluada depende del ambiente específico en el cual se establece.…”

“…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]. The rainfall data in Kuala Jambi District shows that the rain is not evenly distributed throughout the year.…”
