YIELD OF FREESIA CORMS PLANTING MATERIAL DEPENDING ON THE INITIAL PARENTAL FORMS

Freesia planting material propagated from corms often gets infected by viral diseases and rapidly degenerates; due to this problem the paper deals with the issue of generative reproduction of this culture. It also informs about the yield of annual corms planting material, depending on the initial parental forms in terms of quantity and their mass from the crossing combinations obtained in 2015–2016. The highest percentage of corms yield was noted in the combinations: ‘Vega’ × ‘Athene’, ‘Georgy Pobedonosets’ × K-76-3/1, ‘Athene’ × ‘Vega’ – (75,0–85,0 %). The corms obtained with the participation of ‘Georgy Pobedonosets’ cultivar had larger sizes and weight (1,00–1,01 g), as compared with other initial forms.
