Allium cepa L. is considered as one of the most widely consumed bulb vegetable in topical and sub-tropical regions of the world, because of its flavour, in addition to other dietic and medicinal values. Poor onion genotypes are among the major production constrains of this crop in Nigeria. Selection response and half sibs family intra class correlation were used to evaluate intra species interrelationship among some yield quantitative parameters which includes bulb yield per plant, number of leaves per plant, plant weight per plot, number of bolters per plot, bulb yield per plot and soluble solid contents of 30 half sibs families in a local onion cultivated variety. Result indicated that the families differ considerably for most of the traits with wide range of mean and variation in mean performance, there by indicating great variation among the families. The association of characters among these families was good with yield being highly significant and positive while for soluble solid content, although found to be negative for all traits but was also very significant. Heritability was generally high for all traits (above 50%), except for bolter which is very low with value of 0.1444 (14%), showing that the traits within these families have a great potential for breeding and that improvement can be achieve through selection.
