SOUZA, Jean de O et al. Yield of onion genotypes in the semi arid region of Northeastern Brazil. Hortic. Bras. [online]. 2008, vol.26, n.1, pp.97-101. ISSN 0102-0536.

The yield performance of onion genotypes was evaluated in the semi arid region of Northeastern Brazil. The experiments were carried out in counties of different Northeastern States [Mossoró (Rio Grande do Norte), Petrolina (Pernambuco) and Juazeiro (Bahia)], from May to September, 2004. The experimental design was of randomized complete blocks with eighteen treatments and three replications. The treatments consisted of the following onion genotypes: CNPH 6415, CNPH 6047, CNPH 6244, CNPH 6400 Chata, CNPH 6400 Redonda, CPACT 1, CPACT 2, CPACT 3, Granex 429, Belém IPA 9, BRS Cascata, Crioula Alto Vale, Bola Precoce, Primavera, Régia, Valeouro IPA-11, Brisa and Alfa São Francisco. Commercial bulb mean weight and total, commercial and non commercial bulb yield were evaluated. The highest yields were obtained from the cultivars: Brisa (59,8 t ha-1) in Mossoró, Belém IPA-9 (58,9 t ha-1), Régia (58,9 t ha-1) in Petrolina and Granex 429 (27,9 t ha-1), Brisa (26,6 t ha-1), Alfa São Francisco (23,0 t ha-1) and Régia (20,0 t ha-1) in Juazeiro.

Keywords : Allium cepa; yield; adaptation.
