Evaluation of Canola Genotypes Based on Drought Tolerance Indices Download PDF

For evaluation of study the effect of deficit irrigation on some drought resistance indices of canola genotypes, two separately experiments were done in factorial experiment basis of Random Complete Block design with three replications. This study was conducted during 2015-2016 in two provinces (Rostam and Basht). The factors to be studied include 20 canola genotypes and drought stress in two levels (normal irrigation after 80 mm evaporation from pan class A, irrigation stop in flowering stage). Basis grain yield in irrigation (Yp) and stress condition (Ys), calculated quantitative resistance indices such as: SSI, TOL, MP, STI and GMP. TOL was significantly affected by the genotype. Genotype and region had a significant effect on STI, GMP, MP and SSI.
