Morphological and phenological studies in the sweet cherry genebank at NARIC-FRI Research Station of Érd, Hungary

Plant genetic materials maintained in genebanks are outstanding supplementary sources for plant breeding programs.
Studying the phenological and morphological traits of our available resources is essential.
We recorded flowering dynamics of 22 sweet cherry (Prunus avium L.) accessions in two consecutive years.
Flower buds were observed daily on trees, 200-600 on each, and open flowers were recorded.
Using statistical analysis, four blooming groups were identified.
One accession had an earlier blooming date than did the reference cultivar ‘Bigarreau Burlat’. Fruit morphological characterization was performed from 2016 to 2018. Six qualitative and six quantitative traits were recorded of 31 sweet cherries.
Statistical analysis was used to classify accessions using fruit morphological characteristics.
Two main clusters were identified, fruit skin color, and fruit flesh color were determining traits.
Four main factors were extracted using principal component analysis, explaining 83.6% of the total variance.
