Variance and genetic and phenotypic correlations among productivity and its components in Cotton


Abstract in English

Seven cotton genotypes (Rkka5, Aleppo1-33, Aleppo90 – Aleppo 118, Aleppo 40, Deir22, and Line124), were used to estimate variance and genetic and phenotypic correlations between seed cotton productivity and its components [earliness in flowering and maturity(day), plant height (cm), number of vegetative and reproductive branches, number of bolls per plant, 100 seed weight (g), average boll weight (g), lint percentage (%), and plant yield (g)], to be used as selection indices for higher yield performance in breeding programs. The experiment was carried out in Al-Ghab region (Hama) in 2012- 2013 growing season using randomized complete block design (RCBD) with three replications.
