Performance of 'Lana', a new plum cultivar developed at Fruit Research Institute, Čačak
Lana was recognized as a new plum cultivar developed at the Fruit Research Institute, Čačak in 2020. It is the 18th plum cultivar created at the Institute. Lana was developed by planned hybridization of California Blue × Ruth Gershtetter and aimed selection of obtained plum hybrids of early fruit ripening time, good fruit quality, positive pomological properties, regular and optimal yield, and resistance or tolerance to the main plum pathogens. The new cultivar is characterized by a moderately vigorous to vigorous tree, a rare canopy with narrow-pyramidal shape. The branches are well garnished with fruiting wood. Flowering time is medium early similar to standard plum cultivar Čačanska Rana with which it was evaluated in parallel. It is a self-incompatible cultivar. The ripening season is early, occurring in the second decade of July, about 4-10 days after Čačanska Rana. It crops regularly and moderately. In field conditions, under natural pathogen infections pressure, Lana shows no susceptibility to the Polistigma rubrum (Pers.) DC, Puccinia pruni-spinosae (Pers.: Pers.) and Taphrina pruni (Fuck.) Tul, while sporadic symptoms of brown rot can be observed pointing at moderate susceptibility to Monilinia laxa (Aderhold & Ruhland) Honey. Lana is tolerant to Sharka, it could exhibit sporadic symptoms on individual leaves but not on the fruits. The fruit is large, with average weight of 86.34 g, roundish, with very pronounced suture line. The skin is purple-blue with mildly expressed bloom. The flesh is yellow-greenish, moderately firm, juicy and aromatic with sweet-subacidic flavor, having 97.08% of share in the fruit weight. It contains an average of 14.5% soluble solids, 9.95% total sugar and 1.34% total acids. The stone is large and partially separated from the flesh. Lana is a plum cultivar intended primarily for fresh consumption. It is recommended for growing in suitable agro-ecological conditions of vineyard areas.
