| Abstract | ||
| Field experiment was conducted to compare different ten genotypes of corn which produced by combination of double hybrids in order to induce synthetic varieties that consists of four single hybrids The objective of this study was to produce and evaluate synthetic varities which produced by the combination hybrids and to inspect for the suitable varieties for spring season, in addition to extent the genetic base of corn for spring cultivation. Results revealed that the new varieties were superior on the two local combined genotypes in the two spring season for all traits except plant height, number in grain row at two season. Grain yield of genotypes 5, 3, 6 was 4700, 4670.66 and 4614.6 kg/ha in spring season 2006 respectively. whereas genotypes 3, 6, 1 gave grain yield 5787.66 , 5758.66 and 5758.66 kg/ha inspiring season 2007 respectively. It may recommended to submit the best genotypes for registration and release due to its good agronomic performance and yield and its components. | ||
