Asparagus is a species of world importance and Peru is one of the countries with the best production. This high production of asparagus has forced plant breeders to investigate new alternatives to have asparagus cultivars with high yields and quickly. Therefore, research is oriented to the production of male asparagus cultivars using anther culture, since this technique facilitates the selection of genotypes and reduces the time of selection of a cultivar. Therefore, the objective of this work is to evaluate the behavior of the anthers of three asparagus cultivars (ATLAS, IDA LEA and UC 157 F1) under in vitro conditions until obtaining plants. This research realized in the biotechnology laboratory of the PIPs in Cereal and Grain Andean in 2013. The anther culture protocol of three asparagus cultivars was developed (ATLAS, IDA LEA, and UC 157 F1) obtaining the following: (1) The anther state more adequate was when the floral button has between 1.5mm y 2mm to the three cultivars. (2) In the three cultivars, the sugar caused the anther oxidation but incentivized the callus formation (androgenic response), together with the ANA hormone concentration and the ANA/BAP relationship. (3) Only, The UC 157 F1 cultivar produced white callus in the MS induction medium supplemented with ANA (2mg/l), BAP (1 mg/l), and 5% of saccharose and produced 15 embryos and two plants by callus in average with the MS regeneration medium supplemented with 0.3 mg/l de ANA, 0.2 mg/l de BAP and 3% de saccharose. These results reveal that the decrease of ANA, BAP, and saccharose concentration, promote the regeneration of the plants in the asparagus anthers.
