Gavdos (BCH 'S'/SHORK*2/3/CNO 'S'/GLL/BB No4A/K CYA85-81-OD-32P-OP-3P-3P-OP) is a bread wheat variety originated from a cross made at the Agricultural Research Institute (ARI) in 1985. The parents used, were two selected CIMMYT lines introduced in Cyprus through the cooperative program of ARI with CIMMYT, Mexico. The F1 was grown at Athalassa. The consequent breeding methodology used up to F6 generation was a modification of the pedigree method pursuing early-generation selection for quality and yield impovement. Gavdos was evaluated in the multienvironmental testing program of the Institute at a total of 18 environments in five growing seasons (1993-1998). It gave (5930 kg/ha) a significantly higher yield than Karpasia, Pitic 62 and Hazera 18 (12, 14 and 55 higher respectively). Regression analysis of yield data revealed that Gavdos has the most stable grain yield among the tested varieties. Agronomically, Gavdos, is intermediate in plant height at maturity and resistant to lodging. Its heading date was within the first half of March. In all growing environments, Gavdos had better grain hectoliter weight then E.U. standards. Farinogram and alveogram data showed that Gavdos had a similarity strong gluten with Hazera 18. Gavdos gave 100 g loaves of pan bread with average volume 709 cc compared to 707 cc obtained from imported hard red winter wheat. Its milling and bread processing charactristics were comparable to the imported red wheat with strong gluten, in a 1997 commerical testing.
