Pineapple varieties are mainly divided into four categories: queen, Kane, Spain and hybrid. At present, the main varieties of pineapple cultivated in China are mainly the first three categories.

1, the main characteristics of the queen class are:

The plant is tall, with prickly leaves, purplish red flowers, small fruit, deep eyes, small protruding fruit, yellow to dark yellow flesh, sweet taste, less fiber, and good fruit processing, canning and fresh eating. The main cultivated varieties are Empress, Golden Empress, "Philippines" (Bali), Natal, Shenwan and Ruby.

At present, Bali is the main pineapple variety planted in China. Strong growth potential and open plant type; The leaves are broad and green, with white powder on the back, wavy edges, neatly arranged thin and dense spines, and pink lines on both sides of the midline on the back.

Widely planted in Xuwen, Leizhou, Hainan, Qionghai, Wanning and other places.

2. The main features of Cain class are:

The plant is tall and erect, with no thorns at the leaf edge or a little thorns near the tip. The fruit is large, long and cylindrical, with orange-yellow to bronze skin and flat and shallow eyes. Flesh is yellowish to yellow, sweet in taste, moderate in acidity, soft, tough and juicy in fiber; Good processing and canning.

Cultivated varieties are Thornless Kane ("Hawaii" and "Sarawak"), Taifeng and Shilu.

3. Spain:

There are two kinds of plants: spiny and spineless. The plant is medium-sized, slightly spread, with long and wide leaves, light green and reddish leaves and bright red petals. The fruit shape is medium and large, the fruit eye is flat, the fruit eye is deep, and the peel is dark orange and yellow-red; Deep yellow to white flesh; Thick meat and much fiber; The flavor is sweet and sour, the fruit is resistant to storage and transportation, and it is well processed and canned.

Extended data:

storing property

There are three groups of pineapple varieties: Kane, Queen and Spain. Most of the existing varieties are not resistant to storage and low temperature, and only the native varieties of Bali, Wuming, Yunnan and Taiwan Province, which are the queen species, are resistant to storage.

The maturity of pineapple is closely related to its storability. Low maturity, low sugar content, insufficient aroma, light color and low commodity value. In addition, pineapple is a kind of non-climacteric fruit, which can not continue to mature after harvesting.

In addition, at room temperature, fruits in autumn and winter are prone to black heart disease and are not resistant to storage and transportation; Summer fruit and spring fruit are the most ideal varieties for transportation and storage in the north because of their high temperature, perishable and light consumption.

Pineapple is also a kind of tropical fruit which is sensitive to low temperature. Generally, chilling injury will occur below 6℃. Black heart disease is the most common physiological disease in pineapple storage, which is mainly caused by low temperature during fruit growth and storage and transportation.
