A New carambola Variety 'Sweet carambola 3'

We have carried out the breeding of new varieties of sweet carambola since the late 1980s. A single plant and scion of sweet carambola was introduced from home and abroad from 1986 to 1994. in 1992, it was found that the fruit shape and quality of a single plant (No. 94-3) was obviously different from that of the original variety Malaysia B17. Continuous observation and high grafting cultivation experiments from 1993 to 1995 showed that the genetic character of this single plant was stable. The seedlings of this line were bred from 1996 to 1998, and a multi-site regional cultivation experiment was carried out in the suburbs of Nanning, which passed the re-selection and final selection. In May 2007, it was approved by the crop Variety approval Committee of Guangxi Zhuang Autonomous region and named 'Sweet carambola 3'.

Variety characteristics

The tree is slightly weaker, the branches are open, and the branchlets are many and dense, soft and drooping. The compound leaf is long 8~18cm, wide 9~14cm, the leaflet is mostly 9~ll, the leaf tip is pointed. Inflorescences long 2~3cm, single flowers smaller, pale purplish red. The fruit is long and oval, the fruit is thin and the fruit tip is protruding (the fruit of the original variety is thick and the fruit tip is concave). The pericarp is thin and smooth (the original variety is slightly rough and has no luster). The immature fruit is turquoise, the ripe fruit is yellow, and the edge is turquoise. The average weight of single fruit is 183g (original variety 285g). The pulp is fine and crisp, the fiber is less, the taste is sweet, and the quality is better than that of the original variety. Soluble solids 12.6% (1.8% higher than the original variety), total sugar 8.9%, acid O.18%.

There are three or four flowering times a year in southern Guangxi: from mid-late May to early June, from mid-late August to early September, from mid-late July to mid-August, from mid-October to early November, and from late October to mid-November. mature from mid-January to late February the following year.

The faster the growth, the earlier the fruit. In the same year, it blossoms and hangs fruit in the same year, can be formally put into production in the second year, the plant yield can reach 10kg, the plant yield reaches 25kg in the third year, and the plant yield reaches more than 36kg in the fourth year.

Key points of cultivation techniques

It is suitable to be planted in southern Guangxi. Choose the south or southeast middle and lower slopes with loose, fertile and small slopes, and build a garden on a gentle slope. The grafted seedlings were used and the row spacing was 4m × 5m. Use rotten organic fertilizer as base fertilizer before planting. Attach importance to plastic surgery and pruning. When the fruit is the size of the thumb, the fruit is thinned, too many small fruits, deformed fruits and disease and insect fruits are removed, and then bagged.
