| Abstract | ||
| Heat stress has a negative impact on crop productivity and quality. This article aims to evaluated the performance of fifteen sugar beet genotypes were evaluated during 2021/2022 and 2022/2023 seasons at Toshka Station (Latitude 22°28'16.05"N, longitude 31°32'21.01"E and 203 m above sea level), Desert Research Center in Aswan Governorate. The experimental design was a randomized complete block design with three replicates. The results showed that mean squares sugar beet genotypes for leaves weight, root length, root diameter, root weight, and total soluble solids percentage(T.S.S.%) characters were significant in the two seasons as well as for the combined data. Mean performance of G1, G3 and G12 genotypes were the best for root weight and T.S.S%. Root weight had highly significant and positive correlation with each of leaves weight, root length, root diameter and T.S.S%. Root diameter had a significant and positive correlation with T.S.S%. The difference between the two seasons for results is due to high temperatures during second season. This is the first step of program towards selection of suitable sugar beet genotypes for Upper Egypt conditions. | ||
