A new pineapple (Ananas comosus) variety of the Bromeliaceae family was developed from a cross between the parental lines 64-337 (C12Q2SG1P1)x59-443 (C9P3SG2R2) and has been designated 'P-1972'. This new variety differs from its progenitors in having higher carotene content, improved aroma, distinct fruit and flesh colors, and very symmetrical, oval fruit shape. It also shows low incidence of fruitlet core rot and marbling. The plant is characterized by long spineless leaves with piping, pale to grayish green in color, with veins protruding from the leaf surface. The plant has a uniform cylindrical and symmetrical fruit with a smooth and thin shell and flat fruitlets or eyes. Fruit is borne on a peduncle and the crown is long and conical with green to grayish green leaves. When unripe, fruit shell is pale green, turning to uniform yellow color when ripe. The flesh color is orange-yellow to yellow. |
