Title

EVALUATING WATER DEFICIT TOLERANCE OF ADVANCED WHEAT LINES UNDER RAIN FED CONDITION

Pages

  39-51

Abstract

 To evaluate morpho-physiological traits of 14 advance bread WHEAT lines and two local check varieties (Sardari and Azar-2) against drought and their relations to grain yield, an experiment was carried out in a RCBD with 3 replications under both RAIN FED and supplementary irrigation conditions at Maragheh Agricultural Research Station during growing season of 2008-9. To quantify drought response of genotypes, several indices such as SSI, TOL, MP, GMP and STI were applied. Analysis of variance showed that environment × genotype interaction and effect of genotypes were significant at 1% level of probability. Based on the results obtained under rain-fed condition, lines number 8 and 16 had 2080 and 2217 kg/ha respectively, while under supplementary irrigation line number 7 produced highest grain yield (3525 kg/ha). Results indicated that line number 16 had the highest GMP, MP and STI value whereas line number 12 had the lowest TOL value. Correlation analysis of grain yield with stress TOLERANCE INDICES revealed that GMP, MP, STI had high positive correlation with grain yield in both conditions. It can be concluded that these indices are the most suitable measures to identify drought resistant lines.
