Abstract

Using drought and salinity tolerance indices for the identification of SUGAR BEET breeding populations, three trials were laid out in Karaj based on randomized complete blocks design with 10 populations and two controls with three replications under normal, drought and salinity conditions. The electronical conductivity of soil was measured 18 mmohs/cm2 in saline conditions in 30cm depth. The non-stress plots consisted of irrigation regimes (50-55% Field Capacity) and in the drought stress conditions with 85-90% depleted available water (wilting point). Statistical indices such as stress susceptibility index (SSI), stress tolerance index (STI), mean productivity (MP), geometrical mean productivity (GMP) and harmonic mean (HM), were used for WHITE SUGAR YIELD at two stress conditions. The correlation coefficients resulted a high relation for WHITE SUGAR YIELD between STI, HM, GMP and MP indices at drought stress conditions. The high correlation coefficients were estimated for SSI and STI (p£0.01) with the other indices in salinity conditions. The improved genotypes with high yields in stress conditions, recognized by drought tolerance indices. The second generations of populations BP-Mashhad and BP-Karaj were identified as genotypes with high potential for WHITE SUGAR YIELD in DROUGHT CONDITIONS, and for salinity stress the third generation of 8001 and the second generation of BP-Karaj were tolerant. Population 191 showed the lowest yield in both stress conditions but the highest performance in non-stress.
