For this purpose, to investigate the effect of drought stress on yield and morphological traits of sugar beet and the relationship between these traits with yield in greenhouse conditions, 140 sugar beet genotypes under greenhouse conditions in Karaj Sugar Beet center in 2015 were evaluated for yield traits. The results showed that the effect of genotype was significant for all traits except of leaf area and relative water content, indicating that there was different among genotypes. Drought stress decreased all traits but this effect was not significant on root dry weight, shoot dry weight and total dry weight. Also, petiole length had a positive and significant correlation with root and shoot dry weight and root length in drought condition but under normal condition, no significant correlation observed. It seem...

Significant differences were observed in plant height, flag leaf node until spike distance, grain length, 1000 grain weight, harvest index and hectoliter weight under normal
