Abstract:
Phenotypic selection, although considered as traditional breeding method, is an indispensable technique in crop improvement. Hence, this study aimed to 1) select superior clones of MD-2 pineapple (coined as MD-2 Prime) through phenotypic selection and 2) evaluate and compare the chemical properties of MD-2 Prime pineapple fruits with other pineapple cultivars (MD-2, Del Monte Cayenne, Dole Cayenne and Sensuous) in Bukidnon, Philippines. Suckers (300-350 g) of MD2 Prime were collected from commercial MD-2 pineapple fields at Mt. Kitanglad Agricultural Development Corporation (MKADC), Valencia City, Bukidnon, Philippines. MD-2 Prime and other pineapple cultivars were planted at MKADC Research Field and received similar intercultural management practices. Fruits were harvested at shell color index 3 and chemical properties were evaluated. Based on overall chemical properties evaluated, MD-2 Prime had superior chemical properties (18.67O brix, 0.49% titratable acidity, 38.45 brix and acid ratio and 68.67 mg/100 mL ascorbic acid) compared to other cultivars although Sensuous fruits had the highest brix (20.53O). This implies that pineapple fruit chemical properties were improved through phenotypic selection technique
