1-(Xms/Xmp), in which Xms is the imply worry give of all the genotypes and you may Xmp ‘s the imply non be concerned give of the many genotypes.
Fret threshold list
Where Yp and Ys denote the grain yield of a genotype under non stress and stress conditions, respectively and Xp is the mean yield of all genotypes under non stress conditions.
Mean output
Where, Xs = Yield of a given genotype in a stress environment, Xp = Yield of the same genotype in the non-stress environment.
Tolerance directory
Where Yp = Potential yield of a given genotype in a non-stress environment, Ys = Yield of the same genotype in a stress environment.
Mathematical suggest returns
Mathematical indicate productivity (GMP) for each genotype shall be determined (Fernandez 1992; Schneider ainsi que al. 1997) according to after the method:
Where Yp = Potential yield of a given genotype in a non- stress environment, Ys = Yield of the same genotype in the stress environment.
The above mentioned stress indices were used by the all of our classification to own phenotyping away from mapping communities and you will breeding question to possess tolerance in order to salinity plus sodicity (Pandit ainsi que al. 2010; Ali et al. 2013; Krishnamurthy ainsi que al. 2014, 2016, 2017; Tiwari mais aussi al. 2016).
