چکیده

in order to identify and selection salt tolerant hybrids based on tolerance indices, 17 sugar beet three-way cross hybrids produced by crosses between 17 salinity improved s1 pollinators and a cytoplasmic male sterile (cms) single cross as female, along with three control genotypes were grown in 2007 in rudasht station (isfahan) under saline (12 ds/m and 8 ds/m for water and soil) and non-saline field conditions using a randomized complete block design with five replications. five salt tolerance indices including stress susceptibility index (ssi), stress tolerance index (sti), mean productivity (mp), geometric mean productivity (gmp) and stress tolerance (tol) were used to evaluate the white sugar yield in stress and non-stress conditions. correlation analysis showed that mp, gmp and sti had significantly positive correlation coefficient with white sugar yield under both stress and non-stress conditions suggesting that these indices are more efficient for determining salt tolerant genotypes. based on multivariate biplot, triple plot and cluster analysis, hybrids number 7233-29/19 * (7112*261), 7233-29/35 * (7112*261), 7233-29/34 * (7112*261), 7233-29/28 * (7112*261) and 7233-p.29 * msc2 recognized as salt tolerant genotypes and hybrids number 7233-29/1 * (7112*261), 7233-29/5 * (7112*261) and 436 hybrid were introduced as salt sensitive genotypes. genotype number 7233-29/35 * (7112*261) with highest white sugar yield in stress condition was the best.

selection of drought-tolerant half-sib families in sugar beet

one of the most effective ways to deal with drought stress and increase water use efficiency is the development of drought-tolerant varieties which display less reduction in yield per unit water reduction. therefore, the breeding of diploid pollinators was considered as an essential measure for producing drought-tolerant hybrids. in this study, from 4 diploid pollinator populations, 45 half-sib...
