Abstract in English
Twenty four genotypes were tested for grain yield in four diverse locations
over two seasons i.e. 2005-06 and 2006-07. The genetic material contained 19
promising lines and five checks representing the local and improved cultivars
for Zoon B (250-350 mm/year) in Syria. The results showed the significant role
of the genotype by environment interaction of crossover type in the
performance of the genotypes studied and their ranking across test
environments.
The largest portion of the variance due to GE interaction was
attributed to genotype by season GS and Genotype by location by season GLS
interactions which revealed the importance of selection for yield stability in
addition to average yield across environments.
