| Abstract | ||||
| Hybrid production under Egyptian conditions comes in the first order for Plant Breeding and Conservation Program of Desert Research Center (DRC). A Line × Tester design was used to evaluate heterosis for growth, yield, and quality traits. Three parents (monogerm) with one taster (multigerm) and three hybrids of sugar beet were evaluated during season 2023-2024 at Kafer El-Sheikh governorate. The experimental design was randomized complete block design with three replicates. The results indicated existence of significant differences for most studied traits of sugar beet genotypes. P3 and P4 were the best in most of traits. Heterosis was present for root yield and quality traits of hybrids. P3 × P4 expressed highly significant and positive heterosis to mid parent for root length and root diameter (7.62 and 3.62%, respectively). P2 × P4 expressed highly significant and positive heterosis to mid parent for sucrose percentage (3.19%). Heritability in broad-sense was high for all studied traits, except sucrose percentage was moderate. | ||||
