Avaliação dos acessos de alho coleção do Instituto Agronômico de Campinas

Fifty accesses from the garlic germplasm bank of Instituto Agronomico de Campinas were evaluated in Tiete and Jundiai, Sao Paulo State, Brazil. The field trials were carried out in 2003, and the experimental design was randomized blocks with three replicates. The data were subjected to an ANOVA and the means compared using the Skott-Knott test at a 5% probability level. The access Piedade and Gigante de Curitibanos showed excellent performance for yield and bulb quality in both locations. On the other hand, environmental interaction occurred for access Bulbilho Aereo 2 and Andradas Manoel Lopes 2. For the first one, the bulb size was different and for the second the yield changed. A greater genetic diversity on yield and bulb diameter was observed in Jundiai, due to lower environmental effects.
