Selection of Canadian potato clones for agronomic and frying quality traits, in South of Brazil
REVISTA LATINOAMERICANA DE LA PAPA(2020)
摘要
The strong demand in the Brazilian potato chain for processing frozen French fries varieties, lead us to evaluate the adaptation of Canadian potato clones to the south of Brazil. We evaluated eleven clones belonging to the Center de Recherche Les Buissons, QB, Canada, and the cultivars Asterix and Markies (controls). Experiments were carried out in Pelotas, RS, and Canoinhas, SC, Brazil, in the spring season of 2019. The experimental design was a completely randomized blocks with four replications of plots composed by two rows with 10 plants each. Agronomic and frying quality traits were evaluated. Component traits of tuber yield and of frying quality, plant vigor and maturity were evaluated. Besides, in Pelotas, late blight (Phytophthora infestans) incidence was assessed. Individual and jointly variance analysis of variance, grouping of means and correlation analysis were performed on the data. The clone BGB 476 stood out for high tuber yield, mainly in Canoinhas, as well for good fry quality. The BGB 476 clone stood out for agronomic traits and for frying quality traits.
