Ammi Model Analysis of Stability and Adaptability of Finger Millet (Eleusine Coracana) Genotypes in Southern Ethiopia (Published)
Multi-location study was conducted at locations namely Jinka, Kako and Alaba in two consecutive years (2011 and 2012 G.c) to identify high yielding, disease resistant/tolerant and stable performing finger millet genotype for potential areas of Southern region. The trails were arranged in a randomized complete block with three replications. Tadesse was used as standard check along collections screened (Six finger millet genotypes). The experimental plot size for was 5mX 7.5(37.m2). The spacing between rows was 45 cm and 15 cm between plants after thinning. The standard agronomic practices were applied equally according to local agro-ecological conditions. The grain yield in qt/ha with 14% moisture was measured. Additive Main effect and Multiplicative Interaction (AMMI), Genotype and Genotype by Environment interaction (GGE) biplot analysis model revealed that environment effects and genotype effects were highly significant implies environments are diverse and genotype were performing differently. According genotype LR004 &LR005 showed stable and above mean performance across testing location and season. So this varieties should taken for verification trial with standard checks (recently released varieties) under locations were regional variety trials were conducted.
