Annona atemoya is originated as a cross of Annona squamosal and Annona cherimola in Florida. P.J. Wester made the first cross at the United States Department of Agriculture’s subtropical laboratory, Miami in 1908. In 1910, seedlings were planted. Other crosses was made in 1910 and fruited in 1911. Then seeds were taken to the Philippines and other by Wester. The plant does well in the lowlands in warm tropical to subtropical areas. The optimum growth occurs at the minimum temperature of 13–20°C and a mean maximum of 22–32°C. For the fruit maturation, it requires the optimum temperature from 22°C to 26°C. It cannot tolerate frost and young trees are damaged by low temperatures of 4°C and subzero temperature causes the fruit splitting and discoloration. It thrives well in areas with 70 to 80% relative humidity and with adequate rainfall that occurs during the growing period. It is vulnerable to strong winds due to shallow rooting system and wind break is essential. It prefers sandy and loamy soils but grows on red basalt or well-structured and well drained clay loams.
Plant description
Atemoya is a small tree which grows to the height of 8 meters with short trunk and low drooping branches. Leaves are alternate, deciduous, leathery, elliptical and slightly pubescent measuring 15 cm long. Flowers are solitary, axillary which forms in clusters of 2 to 3, triangular, yellow and 6 cm long by 4–5 cm wide. Flowers has convex or cone shaped receptacle which contains numerous carpels at the top half and androecium in the lower circumference of the receptacle which is encased by 3 to 4 sepals. Fruit is a fleshy syncarp formed by fusion of carpels and receptacle. Fruit is heart shaped or conical, 8–12 cm long by 9–10 cm wide weighing 2–2.5 kg. Fruits are pale bluish-green to pea-green and slightly yellowish between areoles. Rind is 3–4 mm thick which consists of fused, prominent and angular areoles having rounded and slightly upturned tips, pliable, firm and indehiscent. Flesh is fragrant and solid divided into segments having few seeds than sugar apple. Seeds are hard, smooth, cylindrical and about 2 cm by 1 cm.
Leaves are hairy and green when young and become smooth when mature. It is elliptic, ovate or lanceolate in shape. Leaves are 4 to 8 inches (10-20 cm) long and 1.5 to 3.25 inches (4–8 cm) wide.
Flowers
Flowers arise during mid to late spring. Flowers form singly or in 2-4 clusters from leaf axils on one year old shoots or new growth. Flowers are green with fleshy petals and 3 small and inconspicuous sepals and unicarpellate pistils on common receptacle.
Fruit
Fruit is conical to ovate and about 3-5 inches in diameter weighing 8 to 32 oz (227–908 g). The surface of the fruit is smooth, bumpy and possesses pronounced protuberances. The color of the fruit changes from green to yellowish green as the fruit matures. Pulp is white or creamy with custard like consistency and sweet or pleasant flavor. The fruit has 10 to 40 small, shiny and dark brown seeds.
Origin
The first cross was formed by P.J., a horticulturist in 1908. In 1917, the hybrid fruit was grown at the Plant Introduction Station in Miami, Edward Simmons. The tree survived at 26.5ºF temperature showing the hardiness.
Health Benefits of Atemoya
