Major criteria for choosing walnut cultivars suitable for growing in Bulgaria
Keywords:
cultivars; cultivation; evaluation; Juglans regia; walnutAbstract
Choosing walnut cultivars suitable for growing in Bulgaria is of great importance for the development of walnut production in the country. The present paper describes the major criteria for their assessment. It was concluded that the cultivars to be grown in industrial walnut plantations in the country should be characterized by: moderate tree growth, late flowering period, early and lateral fruit bearing, high yields, pale coloured and fat kernels of 7 – 8 g in weight, high winter hardiness of the fruit buds, resistance or tolerance to walnut blight (Xanthomonas campestris pv. Juglandis) and anthracnose (G. leptostyla) and top quality oil.
