Synopsis

Synopsis

Plot error variances were large for lint yield, bolls per plant, seed per boll, and boll weight; small for lint percentage, seed and tint index, and fiber length, strength and fineness. Genotype x environment interaction variances were generally small for all traits except yield and bolls per plant. Lint yield was highly positively correlated with lint percentage and bolls per plant and negatively correlated with seed index and weight per boll.
