2008

This study was conducted at Eilafon Area, Bahri Governorate Khartoum State, under cooled plastic houses conditions, with the objective of evaluating the adaptability and productivity of six indeterminate tomato cultivars. Normal and cherry tomato varieties were tested. The normal varieties were Chanoa, Merel, Sensie and Yusra, and the cherry varieties were Tomi and Elitrros. The study was conducted during summer season 2007 in two different locations. The parameters assessed in this study were plant height (cm), number of leaves/plant, number of internodes/plant, number of clusters/plant , number of flowers/inflorescence, number of fruits/cluster, number of fruits/square meter, fruits weight/meter square, and fruit diameter (mm). The results showed that Merel cultivar had the highest plant height and highest number of leaves and internodes per plant while Elitrros cultivar produced the highest number of branches/plant. The cultivars, Tomi and Elitrros recorded the highest number of fruit clusters while the Elitrros cultivar recorded the highest number of flowers and fruits per cluster. Chanoa cultivar recorded the highest number of fruits per square meter. Regarding productivity, Chanoa exhibited the highest productivity (256.3 tons/ha) followed by Elitrros (247.5 tons/ha) and Yusra (241.3 tons/ha). Yusra cultivar recorded the highest fruit diameter (60-70 mm). In the cherry group, Elitrros cultivar (247.5 tons/ha) showed highest growth and yield parameters compared to Tomi cultivar (206.3 ton/ha). However, the productivity of both Elitrros and Yusra was almost similar. However, since Yusra is a normal sized tomato it might have economical advantage over Elitrros ion local markets as cherry tomato cultivars are not of similar popularity
