Characterization of wheat (Triticum aestivum) for stay green trait
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 1
Abstract
Stay green trait is one of the major character of the crops like wheat, rice etc. to sustain under abiotic stresses. In the present study, 10 wheat varieties were collected to develop the stay green genotype by treating them with 0.5% Ethyl methanesulphonate (EMS) for 60 minutes. The various morphological and physiological characteristics such as: plant height, leaf area, numbers of productive tillers/plant, seeds per spike, 1000 grain weight, related water content (RWC), chlorophyll content etc. were recorded under controlled and treatment conditions. Exceptionally, K 7410 and RAJ 3765 varieties showed better value of all morpho-physiological characters among all the ten wheat varieties in control and treatment like 1000 grain weight 58.50 to 60.89g and 56.89 to 58.07g etc. Such mutants of these two varieties may be considered as stay green mutants and can perform better under abiotic stress conditions like drought, high temperature.
