The experiment was carried out during 2018-2020, with 5 varieties of Pisang awak banana Hung Yen Pisang awak, Thailand Pisang awak, "Phan vang" Pisang awak, white "Xiem" and black "Xiem" were arranged in a completely randomized block design, 30 plants/1 variety with three replications. The obtained results showed that the experimental Pisang awak banana varieties had the ability to grow well, have similar fruit quality, and were well adapted to the ecological conditions of Gia Lam - Ha Noi. In which, varieties Thailand Pisang awak, "Phan vang" Pisang awak have similar actual yield and are the highest among the experimental varieties with 36.4 - 38.7 tons/ha in crops 1 and 28. 7 - 31.2 tons/ha in crop 2. Hung Yen Pisang awak banana variety has the lowest actual yield with 21.8 tons/ha in crop 1 and 12.7 tons/ha in crop 2. Varieties Thailand and "Phan vang" Pisang awak had a lower panama disease infected plant rate compared with other varieties grown in the experiment with infected rates of 6.5%, 8% in crop 1 and 18.2%, 24.1% in crop 2, respectively. Hung Yen Pisang awak banana variety had the highest percentage of panama disease infected plants with 45.8% in crop 1 and 65.8% in crop 2.
