Abstract: (1166 Views)
Considering the effect of salinity stress on the quantitative and qualitative traits of sugar beet genotypes, it seems necessary to study the response of genotypes obtained from breeding programs to salinity stress. For this purpose, 17 full-sib genotypes (derived from sibling crossing) with 7 different tolerant control under two salinity stress (electrical conductivity 17.36 dsm) and without stress conditions, in a completely randomized block design with 3 replicates were studied at Miandoab Agricultural and Natural Resources Research Station in 2017. The results showed that salinity increased sugar content, alkalinity coefficient, percent of sugar extracted, molasses sugar, sodium content, potassium content, leaf freshness index and relative water loss and decreased root yield, net sugar yield, sugar yield, leaf area, shoot fresh weight, shoot dry weight, root dry weight, nitrogen, potassium to sodium ratio, syrup purity and Ratio of weight to root volume. Significant differences were observed among genotypes for leaf area, leaf freshness index, relative water content and leaf specific weight. In root and sugar yield, only a significant difference was observed between full-sib genotypes in normal conditions at 1% level. The full-sib 16, 1, 2, 4, 7, 9, 10 and controls 18, 23, 24 and 25 had the highest and, full-sibs 11 and 12 had the lowest root yield under normal conditions. As the same way, full-sibs 7, 8, 1 and 10 had the highest and full-sib 6 had the lowest sugar yield.
