Testing of strawberry cultivars - indicators defining the yield

Abstract

In this research paper are presented the results from the analysis of the following strawberry cultivars - Ostara, Korona, Pineberry, Maxim, Dora with standard for Cambridge favourite. The experiment began in mid-May, 2015 on experimental fields in Kostinbrod of four sets with 20 plants each, with a planting distance of 1.00 m / 0.25 m. A variety of indicators has been studied for the experiment: number of inflorescences and flowers per plant, count of flowers per inflorescence, average fruit mass and yield. Number of inflorescences and flowers per plant, count of flowers per inflorescence, average fruit mass and yield are the studied indicators for the experiment. It is established that the average number of inflorescences per plant of strawberry cultivars is 5.4. The lowest number has Pineberry (2.5) while the biggest one has Korona – 10.0. The higher number of flowers per inflorescence increase the fertility of the cultivars. The average number of flowers per plant for the tested period is 49.5. The lowest numbers has Pineberry (20.9) and with the biggest is Korona (97.6). The fruit of the white-fruited cultivar Pineberry are very small, the products from Dora are not sufficiently large. However, their high fertility allows for a good yield. The Cambridge favorite, Korona and Maxim are distinguished by their large fruit. It has been established that Ostara and Pineberry have mid yield. The standard Cambridge favorite has very good yield. Excellent yield was found at Korona, Dora and Maxim.
