AN EFFICIENT TECHNIQUE FOR SCREENING WHEAT (TRITICUM AESTIVUM L.) GERMPLASM FOR DROUGHT TOLERANCE IJAZ RASOOL NOORKA AND IHSAN KHALIQ
Abstract:
Effective screening techniques for drought resistance would be
beneficial in wheat breeding programme. Higher water requirement and
increasing labour costs are the major problems of field and laboratory
screening techniques. An attempt to improve the economic and rapid
screening was made in the present study. The investigation was mainly
restricted to seedling response of 100 wheat varieties/lines. Wheat
seedlings were counted to measure the following seedling traits;
emergence percentage, emergence index, emergence rate index, energy of
emergence, mean emergence time, percent seedling recovery and
desiccation tolerance index. These traits when pooled together could
discriminate between drought tolerant and susceptible genotypes. Department of Plant Breeding & Genetics, University of Agriculture, Faisalabad 38040, Pakistan, E-mail: ijazphd@yahoo.com |
