'Autumn Bliss' raspberry phenology was studied at Guerrero, Chihuahua State, Mexico. In this trail 500 plants of raspberry, bare root system, were planted in the first week of April, 2000. Plantation distances were 1.5 x 0.5 m between rows and plants respectively, in 10 rows with 50 plants each one. Before plantation 60 t·ha-1 of dry bovine manure was applied. Furrow irrigation system was used during the first 30 days. Later on drip irrigation was installed with 1 m between emitters. The new regrowth was from the root system, and from budwood, 30 days after plantation. Primocanes fruiting length was 180 cm. Bloom initiation was in the second week of July, after more than 90 days of growth, with no probabilities of frost damage. Primocanes fruiting number was 6.7 per plant. Period from flower to fruit harvest was between 33 and 36 days. First harvest was on the first week of August, and the last one was late October, just when the frost period started. Fruit size was from 2.6 to 3.6 g. Yield recorded was 778 g·p-1, estimating 10.373 t·ha-1.
