Description The materials of present investigation consisted of two parents viz., Chinese spring
and C591 and selected 8 disomic chromosome substitution lines of C591 in the background of
Chinese Spring. The experiment was laid out in completely randomized block design with
three treatments and replicated thrice. The data were recorded for different field traits and
computational traits of selected 8 disomic lines, their parents and WH147, WH147M. The
data for AGPase activity suggests the localization of gene on different chromosomes. It also
suggests no. of copies for gene of AGPase enzyme are located at specific chromosome, active
at different grain filling stages.
Analysis of variance revealed the presence of significant variability in the materials
under study. Observations recorded on yield and its attributing characters and macro and
micronutrients contents as well as their plant uptake revealed genotype and chromosome
specific variation. On the basis of genotypic performance under various treatments for
different plant characters, macro and micro nutrients uptake and Azotobacter colony count,
disomic chromosome substitution lines 1D, 5D, 6B, 7B figured promising. It could be
postulated that the quantitative trait loci for high micronutrients uptake and response to
Azotobacter inoculation were present on 1D, 5D, 6B, 7B chromosomes. This indicated good
scope for wheat improvement through analytical breeding at chromosome level.
