- This study was undertaken to estimate genetic variability and heritability of some morphological and agronomic parameters to discriminate some cotton genotypes in collection in field. The experiment was carried out in randomized complete block design with three replications at site of experiment of Cotton and Fibres Center for Agricultural Research at Cana located in south of Benin during 2010-2012.Analysis of variance showed highly significant (pigh heritability values were obtained for three discriminant agronomic parameters (BVB:0.986; BFB:0.950; RP1:0.987). Genetic advance was ranged from 7.99% (BVB and BFB) to 15.72 (RP1). Highly significant positive correlation was observed between agronomic traits (number of bolls on vegetative branches, number of bolls on fruiting branches) and morphological traits (length of vegetative branch, length of fruiting branch, plant height to first fruiting branch and plant height). Results also indicated that length of vegetative branch, length of fruiting branch, plant height to first fruiting branch and plant height were good predictors of boll production. The observed extensive variation and high heritability provided with relevant information for further improvement programs.
