If we compare the two varieties Roclas and Christian, the height ofplantlets (Fig. .) for Christian cultivar can say that has responded better than gettingRoclas potato plantlets (plantlets height was bigger in all cases).The statistical interpretation of results of the plantlets heightFrom assessment results, it is noted that the Christian cultivar exceededthe average value of Roclas cultivar, the difference was not statistically,insignificant, negative, -0,661 for Roclas cultivar (Table 3).Table 3 .
