Determination of Drought Tolerance for Some Cotton Genotypes (Gossypium hirsutum L.) under Deficit Irrigation Conditions
Abstract
The aim of this study was to use water more
efficiently and determine
drought-tolerant cotton genotypes by reducing the irrigation water at certain
rates. In this study, 7 different cotton genotypes (Aday 1, Aday 2, Aday 3,
Aday 4, Aday 5, Aday 6, and Aday 7) and a control variety (Stonville 468) were
used. In order to determine drought tolerance, parameters including Stress
Susceptibility Index (SSI), Yield Stability Index (YSI), Yield Reduction Ratio
(Yr), Yield Index (YI), Tolerance Index (TOL), Mean Productivity (MP), Harmonic
Mean (HM), Geometric Mean Productivity, Modified Stress Tolerance (K1STI- index
calculated from potential yields, K2STI- index calculated from yield values in
stress conditions) Stress Tolerance Index (STI) and Yield Strength Index (YSI)
were used. Stressed and non-stress conditions applicability of HM, MP, GMP,
STE, K1STI indices has appeared in Aday 4 genotypes. The highest value of MP
was found in Aday 6 genotype. The lowest SSI index was in genotype Aday 2. As a
result of the mean comparison (LSD), principal component analysis (PCA) and
cluster analysis, the Aday 2 genotype was found highly tolerant to drought
under non stress conditions.
