dc.description.abstract | The present study was undertaken to determine the genetic variability for quantitative traits and their association contributing to seed yield and physiological efficiency under water deficit conditions with the objective of exploring possibilities of water stress tolerant and physiologically efficient genotypes. The material for present investigation comprised of 25 guar genotypes. The experimental material was grown at research area crop physiology (agronomy), CCSHAU, Hisar during Kharif 2010 in randomized block design with three replications. Observations were recorded for 18 morphophysiological and biochemical characters. Considerable amount of variation was found for all the characters studied, seed yield was found positively correlated with number of pods per plant, dry weight, 100-seed weight, harvest index, seeds per pod, chlorophyll fluorescence, canopy temperature depression, leaf area index, plant height and negatively correlated with rate of water loss from excised leaf. Path analysis revealed maximum positive direct effect of dry weight on seed yield followed by harvest index while plant height, branches per plant and 100-seed weight had negative direct effects. Genotype HG 2-20, HG 884, HG 2-1exhibited highest yield and physiological efficiency evaluated on the basis of seed yield and dry matter accumulation per day. These genotypes can be considered as physiologically efficient and water stress tolerant and can be used for future breeding porgrammes. | en_US |
