| Abstract |
Background and Objective: Crop genotypes must go through costly multi-environment experiments (METs), which need suitable test
sites to enhance cost effectiveness. This research aims to establish an effective and representative ecological zoning division to enable
practical sugarcane cultivar choices. Materials and Methods: The experiment made use of a Randomized Complete Block Design (RCBD)
with four replications. The studies were conducted at 22 test sites throughout the nationʼs sugarcane-growing areas. Eight sugarcane
genotypes, comprising five genotypes and three commercial checks, were evaluated in this research. Hierarchical clustering or cluster
analysis was done to determine the differences between these locations. Results: Based on optimal genotype ranking, Kps 01-12 (G8)
and KK3 (G6) were the best performers, having a high mean yield and outstanding stability in the examined environment. Test site
grouping was developed with the intention of constructing test sites with negligible G×E interactions to choose a representative site
from each group for actual testing. Due to location groupingʼs ability to capture the majority of G×L interaction, truncation at 12 groups
was recommended by the high R-square achieved. Conclusion: By reducing the 22 locations to 12 sites, which would considerably save
costs and time, the METs of sugarcane genotypes in Thailand may be improved. |
