This study was carried out to develop required genetic variation for. southern dry and warm zone (Zone ll) from crosses made between different bread wheat genotypes. Two hundred and twenty genotypes as parents were categorized in the crossing block based on different traits and characteristics. Each genotype was sown in two sowing dates with 15 days interval, in 2005 - 06 cropping season and 423 crossing program were carried out. Female parents were emasculated in spring and after 48 to 72 hours were pollinated by pollens of concerned male parents. Hybrid seeds for each crossing program were harvested separately to be grown and evaluated, in the presence of concerned parents, in the following cropping season, 2006-07. Seeds of F 1 (103 simple crosses and 61 three way crosses) from crosses made in the previous cropping season (2004 - 05) were also grown and evaluated. Harvested F2 seeds were considered to be grown in southern warm and dry zone field stations in 2006-07.
