Physicochemical, Biochemical and organoleptic analysis of pineapple cultivars MD2 and MORRIS

According to Malaysian Pineapple Industry Board (MPIB), pineapple industry is one of the important agricultural sectors in Malaysia thus plays a role in national earnings as one of the world top pineapple suppliers. In Malaysia, pineapple cultivars include Maspine, Morris, Morris Gajah, Gandul, Sara...

As a conclusion, 'MD2' compares very well against 'Morris', hence its cultivation in Malaysia for potential local and international market should be encouraged not only due to their higher consumers' preference but nutritional benefits.
