Productivity and Quality of Nine Cabbage Varieties In Northeast Sonora, Mexico

In the north of Sonora, Mexico, it is possible to obtain high yields and quality in cabbage production in the cycles of spring, summer and autum-winter. However, are needed seed varieties adapts the temperature conditions of these seasons that have a high potential for quality and yield. The objective of this experiment was to evaluate nine varieties of cabbage. The evaluation was carried out in the INIFAP-CIRNO Experimental Stación (Magdalena of Kino, Sonora) in winter 2004 under field conditions. The evaluate varieties were: Discovery, Charnant, Atlantis, Izalco, Blue Pak (Harris Moran), Red Sun, Blue Dinasty, Blue Pak (Ferri Morse) and Tlixco. The date seedling trasplant establishment was on Febraury 17, 2004. We used a plant density of 57,000 plants/ha in furrows with two rows using drip irrigation system. In this trials, we used a completely randomised desing with four replications. The measured  variables were yield, head weight and head diameter. The harvest period was 9 to 27 June. The results indicated that the highest yield were obtained from:the varieties:Discovery, Charmant, Atlantis and Izalco with 100.7, 97.5, 87.7 and 85.7 t.ha^-1 respectively. The highest head weight were obtained from Discovery, Charmant, Izalco and Atlantis with 1.7, 1.5, 1.5 and 1.4 kg, while what the highest head  diameter corresponded to Discovery, Atlantis, Blue Pack (Harris Moran) and Red Sun with 16.5, 15.5, 15.0 and 15.0 cm respectively.
