Abstract

Breeding cotton for stress tolerance is a priory of most cotton breeding programs. One of the stresses for cotton is cold that affects lint and yield quality. A total of 95 cotton genotypes belonging to G. hirsutum L. were screened at 5 different laboratory tests to determine the best screening test to predict field emergence. Field emergence percentages ranged from 38% to 77% for the 28th day after planting. A standard germination test was performed at 30oC. Cool germination percentages were measured at 13oC, 15oC and 18oC. Multiple regressions were used to determine the degree of association between variables. Predicting field emergence with combinations of 30oC and 18oC tests was better than other tests alone.
