Half-sib analysis in guava (Psidium guajava)

Abstract

The half – sib analysis was carried out in the progenies of guava variety Apple Colour to get information on variance, genotypic and phenotypic correlation, heritability and coheritability. The progenies of Apple Colour X Arka Mridula, Apple Colour X Beaumont, Apple Colour X Chittidar and Apple Colour X Allahabad Safeda were evaluated for fruit weight, fruit volume, fruit length, fruit volume, fruit breadth and TSS. The genotypic variance was less than the phenotypic variance for all characters showed positive correlation except TSS, which had high coheritability values. The study shows that by going in for selection, fruit characteristics can be improved.
