Colomba potato variety (Colombo)
Colomba is a potato variety (Solanum tuberosum) that ripens very early. The people for this potato stuck with the name "Colombo". Bred in the Netherlands by employees of the agricultural company HZPC HOLLAND B.V. Obtained by crossing the varieties of Dutch origin Carrera and Agata. Included in the state register of the Russian Federation in 2013. Approved for cultivation in five regions of Russia - North-West, Central, Volgo-Vyatka, Central Black Earth and North Caucasus.
The growing season is only 60 - 65 days. The first digging can be carried out on the 45th day from germination. So, when planting seed at the end of May, the first harvest can be obtained as early as mid-July.
Plants of a leaf type, of medium height, from semi-erect to spreading. Leaves are green, medium to large in size. The flowers are white. The intensity of anthocyanin coloration on the inner side of the corolla is very weak or absent at all.
Tubers are rounded, medium to large, with yellow flesh. The depth of the eyes is shallow and medium. The peel is light yellow, smooth. Marketable tuber weight - 85 - 130 grams. The average number of tubers in a nest is 12 - 15 pieces.
The yield of marketable tubers is 224 - 422 c / ha, which is at the level of the Pushkinets standard and by 119 c / ha higher than the indicators of the Goryanka standard. The yield indicator on the 45th day after the emergence of full shoots (during the first digging) is 111 - 345 c / ha, which is 40 - 212 c / ha higher than the indicators of the Dolphin, Bryanskiy early standards; on the 55th day (second digging) - 244 - 364 c / ha, which is 62 - 186 c / ha higher than the standards Zhukovsky early, Bryansk early. The maximum yield is 422 c / ha, which is 119 c / ha higher than the Goryanka standard (data for the Stavropol Territory). Marketability 81 - 98%. Keeping quality 95%.
Table variety with high taste. Boiled potatoes are slightly crumbly. The pulp does not darken during cooking. Starch content 11 - 15%, dry matter - 16.9%.
The rest period is short. Tubers are stored for no more than six months.
Colomba potatoes show resistance to the causative agent of potato cancer and golden potato cyst nematode, moderately resistant to common scab (6.5 points out of 9) and the causative agent of late blight (for tops - 4 points out of 9, for tubers - 6 points out of 9). Also shows resistance to darkening of tubers from impacts. Drought resistance is at an average level (5 points out of 9).
Planting these potatoes in too cold soil should be avoided. It is advisable to break off the apical shoots before planting. The variety responds well to the addition of manganese and magnesium. With additional irrigation in dry weather, yields are increased. Excessive moisture loss in tubers and premature germination can be caused by mechanical damage during harvest.
Advantages of Colomba potatoes: high and stable yield, uniformity of tubers, ultra-early ripening, high taste properties.
