Abstract

An experiment was conducted under controlled-conditions to investigate drought tolerance GERMINATION in COTTON. Factorial combination of 40 COTTON genotypes and 3 drought levels (-1,- 4 and-8 bars) were used in a complete Randomized block design 3 replications. Osmotic potentials were created using PEG6ooo. GERMINATION components (rate, uniformity and total GERMINATION) were evaluated in Petri-dishes and seeding growth (root, shoot and total dry weight) in paper towels. Results showed that root shoot ratio increased with decrease in osmotic potential, the greatest root shoot ratio was obtained at - 8 bars. Other traits decreased with decrease in osmotic potential. Shoot dry weight showed the greatest decrease among the evaluated traits. The genotypes Tabeladia, Bulgar 433 andam early maturity mutant in GERMINATION test and genotypes Bulgar 433, Barbadens and Siokrain seedling growth test were detected tolerant to drought and genotypes temer-14, N.O. 259 and A.S.J.2 syland in GERMINATION test and A.S.J.2 x syland, Delta pine and 43221 in seedling growth test were found sensitive. These genotypes can be used in breeding programs of COTTON for drought tolerance.
