Abstract

Under the INSA Fellowship  Programme  (2015), thirty genotypes of Maize which   included  twenty  eight   inbred  lines  and  two  checks   maintained at D(K)ARS,  SKUAST-K were used for a   "Comprehensive Assessment of Drought Tolerance" in the Department of Crop Physiology, University of Agricultural Sciences, GKVK  Bangalore. In this programme the genetic variability for Roots, Water Use Efficiency and Photosynthesis related traits studied to identify contrasts for trait based introgression for drought tolerance. Maize accessions revealed a significant genetic variability for roots, WUE (∆13C). Further significant genetic variability in WUE at single level was also observed. Significant genetic variability in drought tolerance traits was revealed among the maize germplasm lines. The promising lines identified like KDM-932A for root length, KDM-1095 for root volume, KDM-918A for root weight, KDM-954 for epicuticular wax content and KDM- 944A for WUE can be used as trait donor lines to transfer specific traits into a recipient  genotype.
