Fruit variability and correlation analysis of some phenotypic characters in avocado (Persea americana Mill.), rambutan (Nephelium lappaceum L.) and sweetsop (Annona squamosa L.)

Abstract

The fruit characters of 100 genotypes each of avocado (Persea americana Mill.), rambutan (Nephelium lappaceum L.) and sweetsop (Annona squamosa L), propagated using seeds, were evaluated and analyzed. The variability is wide for fruit weight, length and width, seed weight and peel thickness in avocado; fruit weight and length, seed weight total soluble solids and percent edible portion in rambutan; and fruit weight, length and width, total soluble solids and percent edible portion in sweetsop. Conversely, the variability is narrow for flesh thickness, seed weight, length, peel weight and percent edible portion in avocado; fruit width, flesh thickness, seed length and width and peel weight in rambutan; and flesh thickness and total seed weight per fruit in sweetsop. Fruit weight, the most important character being considered in the selection of elite genotypes, is correlated with fruit width and seed weight in avocado, fruit length, fruit width and seed weight in rambutan, and fruit width and flesh thickness in sweetsop. Other character combinations that are correlated are: flesh thickness and percent edible portion in avocado, fruit length and fruit width in rambutan, and fruit width and flesh thickness in sweetsop. The frequency distribution of fruit weight is positively skewed towards the lower fruit weight values in avocado, rambutan and sweetsop.
