he study seeks to examine the multi-locational trail of fifteen genotype of shrunken-2 super sweet maize in benin city. The experiment was conducted at experimental farm with the premises of university of benin teaching hospital. Benin city, nigeria fifteen super sweet corn (maize) genetype “UISSH 1, UISSH 2, UISSH 3. UISSH4, UISSH 5, UISSH 6, UISSH 7, UISSH 8, UISSH 9, UISSH 10, UISSH 11, UISSH 12, UISSH 13, UISSH 14 and UISSH 15 varieties were evaluated in this experiment. The experiment was laid out in a randomized complete block design with three replications. The data collected was analyzed using Genstat version 12. Characters measured included Seedling emergence all 11 days, days to 50% tasseling, day to 50% silking, days to 50% pollen shedding. Ear height, plant height, number of, days to maturity, Number of cob, cob weight, husk cover, ear aspect and fresh ear yield. The effects of genotype (G) were found to be highly significant (p<0:01) days to 50% tasseling, days to 50% pollen shedding, Ear geight. The result of experiments showed that there was significant difference due to genotype effect in plant height, days to 50% tasselilng, days to 50% pollen shedding, ear height, plant height and days to maturity. Genotype also affects days to Cob number, cob weight and fresh ear yield. The genotypes, UISSH3 was identified as one of the most promising for production Benin city although this variety can be improved for early emergence and better
