KẾT QUẢ KHẢO NGHIỆM 10 CON LAI F1 CÀ PHÊ CHÈ TẠI CÁC TỈNH TÂY NGUYÊN

One set of arabica coffee consisting of 10 F1 hybrids were evaluated on the growth and productivity in Dak Lak, Dak Nong and Lam Dong province. The experiments were designed as Randommized Complete Block Design (RCBD). The experiments of F1 hybrids consisting of 11 treatments: TN1, TN2, TN3, TN4, TN5, TN6, TN7, TN8, TN9, TN10 and Catimor as control, were implemented in 2007; yields were observed from 2009 to 2014. The results showed that four F1 hybrids (TN1, TN6, TN7 and TN9) performed good growth, high and stable yield in the growing region; and green bean quality as well as cup quality were far much better than Catimor and the remaining F1 hybrids. Yields of F1 hybrids TN1, TN6, TN7 and TN9 were 2.97, 2.76, 2.94 and 2,95 tons of green bean/ha, respectively; weight of 100 beans were 16.6, 16.1, 16.4 and 16.8 g/100 beans, respectively.
