BREEDING ACHIEVEMENTS ] ON SIBERIAN IRISES IN THE SOUTH OF WESTERN SIBERIA

In conditions of a forest-steppe area in the south of Western Siberia, 12 direct and inverse crosses of 7 cultivars were carried out to obtain cultivars with pink flowers. Progeny of two families had pink hybrids: ‘Lyubimchik Altaya’ × ‘Sultan’s Ruby’ – one hybrid, ‘Reddy Or Not’ × ‘Lemon Veil’ – 15. The number of peduncles in bush varied from 4 to 15, the average – 7.9 ±3.3. Hybrids with 10–15 peduncles are the most adapted and most promising: pink with a white halo – 8–21–14; pink, white border – 1–28–14; light pink, cream border – 7–28–14; lilac, the largest – 18–28–14; pink, border, veins and white styles – 21–28–14; pink, border and white styles – 23–28–14. Only hybrid 34–28–14 is productive, but the color turns out to white strongly, therefore it is unpromising. The average height of the hybrids is 83 ±9 cm; it varied from 70 to 97 cm. The diameters of the flowers varied from 9.0 cm to 12.8 cm, the average – 11 ±1. The width of the lower perianth is 4.5–6.2 cm, the average is 5.2 ±0.7 cm; upper perianth – 2.2–3.7 cm, average 2.9 ±0.4 cm.
