Anousha, a new potato cultivar with high tuber yield and suitable for crisps processing, appropriate for cultivation in spring planting in the cold and moderately cold regions of Iran

Anousha cultivar is results of a cross-pollination of Agria and promising colon 397009, and various field and laboratory experiments during 12 years in the Seed and Plant Improvement Institute Karaj, Iran. To release Anousha variety, single plant selection, visual assessment, preliminary and advanced yield trials, adaptability test, study on resistance to fungi, bacteria and viruses was carried out in different places such as Karaj, Ardabil, Hamadan, Esfahan and Mashhad (Jolgehrokh). Although, Anousha cultivar had superiority to the Agria in terms of yield, but scatter Bi-plot analysis with respect to average yield and relative coefficient of excellence showed that its relative coefficient of excellence was almost the same as that of the Agria. The yield of Anousha cultivar in an on-farm study in Hamadan and Ardabil areas was 12.9% and 12.4% higher than that of Agria (check cultivar), respectively. Anousha cultivar is highly resistant to PVY and PVX that are very important and harmful viruses around the world. The reaction of Anousha to Alternaria alternata, Rhizoctonia solani (race AG-3), Rhizoctonia solani (race AG-4) and Rhizoctonia solani (potato black scurf) is semi sensitive, semi tolerant, tolerant and semi tolerant, respectively. The tuber dry matter of Anousha is 2% more than Agria and is excellent for frying and processing purposes. Anousha as a new potato cultivar is suitable for spring cultivation in the cold and moderately cold regions of Iran.
