Multi-location trials of Waxy Corn Varieties in Thailand

Abstract

Multi-location trials are required for yield performance and stability evaluation of breeding lines. The objective of this study was to evaluate yield performance, stability and agronomic traits of different waxy corn varieties during the rainy season 2006 in Thailand. Twenty-one waxy corn varities were grown at thirteen different locations in the rainy season in/order to determine their performance and stability. A Randomized Complete Block Design with three replications was used. Data on yield and agronimic traits were collected, A combined analysis of variance showed highly significant (P < 0.01) genotype, location and genotype x location effects on yield and agronomic traits. For GGE biplot methodology, based on yields, wx 005 was the most stable genotype.
