ANALYSIS OF GENETIC VARIABILITY PARAMETERS FOR MORPHO-PHYSIOLOGICAL, YIELD AND QUALITY TRAITS UNDER HEAT STRESS CONDITION IN BREAD WHEAT
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 10
Abstract
A field experiment was conducted to study the genetic variability parameters, heritability and expected genetic advance for morpho-physiological, yield and quality traits in bread wheat under late sown irrigated condition in hundred bread wheat genotypes. The analysis of variance for all the morpho-physiological, yield and yield contributing and quality characters revealed highly significant differences except for chlorophyll content reading at anthesis indicate the presence of substantial genetic variation among the genotypes for all the traits. The variability among different genotypes varied highly for all the characters under study. The magnitude of range for Chlorophyll content reading at anthesis was ranged from 45.10 to 55.93 with the mean value of 50.34, canopy temperature at anthesis from 22.48 to 28.75 with the mean value 26.18, days to heading from 47.50 to 74.50 with the mean value of 58.75, thousand grain weight from 11.80 to 47.80 with the mean value of 33.74, protein content ranged from 13.90 to 20.25 with the mean value of 17.25 and sedimentation value varied from 42.50 to 83.00 with the mean value of 60.53. The high PCV and GCV values were recorded for traits like flag leaf width, relative water content, leaf waxyness, number of productive tillers per meter and grain yield, which indicates that, these characters have high variability that in turn offers good scope for selection. The high heritability estimates along with high genetic advance was obtained for flag leaf length, flag leaf width, flag leaf area, relative water content, leaf waxyness, days to fifty percent flowering, plant height, spike length, number of productive tillers per meter, number grains per spike, thousand grain weight, grain yield and sedimentation value. These traits are the most important to be taken into consideration for effective selection in wheat.
