High-Quality Robusta Coffee Lines In Vietnam? Identifying and selecting ingredients from the fruit origin of the crop cultivated in the coffee gardens is the first step in processing high-quality coffee for market supply.
The mature coffee tree bears fruit after three to four years of growth. White blooms that are fragrant and swallowable grow in bunches from the leaf axils of the branches at first. After that, the coffee cherries form long, chain-like gangs. Arabica coffee plants pollinate themselves, whereas Robusta requires cross-pollination. The coffee fruit will progressively ripen and become gorgeous after 30-35 weeks of flowering.
In Vietnam, the Central Highlands Agro-Forestry Science and Technology Institute has selected Robusta coffee varieties for cloning using the young grafting method in the coffee replanting program, including the following primary kinds: TR4; TR5; TR6; TR7; TR8; TR9; TR10; TR11; TR12; TR13; TR14; TR15; TR16; TR17.
* TR4 clone: Vigorous growth, medium height, densely branched, somewhat drooping branches The leaves are medium in size, with a light green tint when young and a green-yellow color when older, with a lanceolate form. Ripe fruits are orange-red, inverted oval shape, and yield 750-800 fruits per kilogram. Medium-sized seeds with a fresh/core ratio of 4.1. One hundred cores weigh 17.1 grams. 70.9 percent grain grade 1. 1.68g/100g dry matter caffeine content The annual harvest time is from November 15 to December 15, and the output is around 7 tons per hectare. Rust disease resistance is high.
Strong growth, medium height, medium branching, drooping branches. *Tr5 clone The leaves are medium in size and rounded, with young leaves that are bright green and older ones that are dark green. Ripe fruits are blood-colored and spherical, with 650-700 fruits per kilogram. Seeds are enormous, with a fresh/core ratio of 4.4, a weight of 100 kernels of 20.6g, and a seed type 1 percentage of 90.5 percent. The yield per hectare is around 5 tons. The harvest season runs from November 1 to November 30 each year. Rust resistance is excellent.
* TR6 clone: vigorous growth, medium height, little branching, horizontal branching The leaves are ordinary, lance-shaped, and the young leaves are bright green, while the older leaves are dark green. Fruits are ripe orange-yellow and spherical, with several fruits per kilogram ranging from 790 to 800. The fresh/core ratio is 4.3, and the seeds are medium-sized. One hundred kernels weigh 17.5g, with seed type 1 accounting for 75.0 percent of the total. 1.95g of caffeine per 100g of dry mass Annual harvest season is from December 15 to January 15, with a relatively good yield of roughly 6 tons/ha. Rust resistance is high.
* TR7 clones have a strong growth rate, are medium in height, and have a lot of horizontal branches. The leaves are medium-sized and lanceolate, with young leaves bright green and older ones dark green. Seven hundred thirty-four fruits/kg of ripe red-pink inverted ovoid fruit. Fresh kernels to kernels ratio: 4.4 100 grains weigh 17.5g, with 72.8 percent type 1 seed—1.85 grams of caffeine per 100 grams of dry mass. The annual harvest time is from November 15 to December 15, and the output is relatively substantial, at 6 tons per hectare. Rust resistance is exceptional.
* TR8 clone: a fast-growing tree with medium height, medium branching, and horizontal branches. The leaves are medium-sized and lanceolate, with young leaves that are bright green and older leaves that are dark green. Ripe fruit with a crimson color, oval form, and knob, with 650-670 fruits per kilogram. The seeds are enormous. The fresh-to-core ratio is 4.4. One hundred kernels weigh 17.6 grams, with seed type 1 accounting for 68.4 percent of the total. Caffeine content: 1.57 grams per 100 grams of dry substance. 6-7 Tons/ha is a very high yield. The harvest season runs from November 15 to December 15 each year. Rust resistance is relatively high.
According to the Central Highlands Agro-Forestry Science and Technology Institute, 98.3 percent of plant kinds are vegetative, with 85.2 percent of seed generated by farmers. Breeding and developing Robusta coffee types is a labor of love. Professional producers, processors, and suppliers must put in a lot of work to comprehend, select, and put into producing and processing high-quality Robusta coffee goods. This includes going to the field, researching, and surveying. Nonstop observation, exploration, and learning
We have other pretty dominating lines in addition to the Robusta kinds described above. Each has its own set of benefits and traits.
* TR9 variety: rapid growth, dark green leaves, blood-colored fruit when ripe, colossal fruit, good rust resistance, over 80% rate of unique seeds, yield 5.5 tons per hectare
* TR11 variety: robust growth, slanting branches, little branching, green-yellow foliage, red-pink fruits when ripe, good rust resistance, over 80% type I seed rate, yield 4, 2 tons/ha
* TR12 variety: robust growth, green leaves, large fruit, red-pink color when ripe, good rust resistance, over 90% special seed rate, yield 4.3 tons/ha
* TR13 varieties have vigorous growth, horizontal branches, dark green foliage, huge fruits that become red-pink when ripe, good rust resistance, a high rate of unique seeds, and a yield of 5.2 tons per hectare.
