MORAIS JUNIOR, Odilon Peixoto de; CARDOSO, Atalita Francis; LEAO, Érica Fernandes  and  PEIXOTO, Nei. Performance of cultivars of cauliflower summer in Ipameri. Cienc. Rural [online]. 2012, vol.42, n.11, pp.1923-1928.  Epub Sep 04, 2012. ISSN 0103-8478.

In order to evaluate the behavior of six cultivars of cauliflower summer, as production and resistance to black rot (Xanthomonas campestris pv. campestris), installed a field experiment in Ipameri-GO, with the experimental in randomized complete blocks with six treatments and four replications. Each plot of 10m2, consisting of 20 plants distributed at a spacing of 1.0m between rows and 0.5m between plants. We evaluated the cultivars: hybrids 'Cindy', 'Sarah AF-1169', 'Sharon', 'Verona', 'Lisvera' and the variety Piracicaba precoce. Hybrids Verona and Sharon proved promising for cultivation in the environmental conditions that were evaluated, with yields of 34.17 and 30.64t ha-1 respectively, and moderate levels of resistance to black rot. The variety Piracicaba precoce showed lower production of the best hybrids and moderate resistance to black rot. The hybrid Sarah is not recommended for planting in the region of Ipameri-GO due to its low production and low resistance to black rot.

Keywords : Brassica oleracea var. botrytis; production; resistance; Xanthomonas campestris pv. campestris.
