Abstract
The study was conducted during three-year period (2020-2022) in a collection orchard of the Fruit-Growing Institute in Plovdiv.
The objects of the biometric analyses were the newly bred sweet cherry hybrids No. 2-24, 4-93, 3-103, 17-37, 17-90 and 28-105, developed as a result of the breeding program, started in 1987. The present study aimed to evaluate the biometric parameters of the sweet cherry hybrids, comparing them with those of the standard cultivars ‘Bigarreau Burlat’, ‘Bing’ and ‘Van’. The average fruit ripening date of hybrid No. 17-90 (‘Asparuh’) was 9 June, just before that of cultivar ‘Van’. The hybrid had the highest average fruit weight (9.96 g) of the entire sample of hybrids and cultivars included in the study, followed by hybrid No. 17-37 (‘Tzvetina’) – 8.74 g.
Both hybrids had the largest fruits with an excellent sensory profile, with high and regular cropping.
It is appropriate to submit them for official registration as new original Bulgarian cultivars.
The selected hybrids No. 2-24, 4-93 and 28-105 are valuable breeding achievements that extend the usual sweet cherry ripening season by a week.
They are genetic donors suitable for use in the next stages of the breeding program for developing very late-ripening hybrids of F2 and F3 generations.
