‘CHEVIGNON’: A NEW WINTER WHEAT CULTIVAR FOR SOUTHERN CHILE

Abstract

‘Chevignon’ is a winter wheat variety developed by ASUR Plant Breeding of France and introduced to Chile by the National Wheat Breeding Program at INIA Carillanca. The variety has medium plant height, intermediate cycle, with resistance to yellow rust (Puccinia striiformis West. f. sp. tritici Erikss), and powdery mildew (Blumeria graminis D.C. f. sp. tritici Marchal), moderate resistance to leaf rust (Puccinia triticina f. sp. tritici Erikss y Henn) and tolerance to septoria leaf blotch (Mycosphaerella graminicola (Fuckel) Sand). It is a high yielding winter wheat variety with good quality characteristics for direct baking. It has a prostrate growth habit at seedling stage, with high tillering production. Its leaves are pale green, with a semi-drooping flag leaf. The spike is white, semi-erect, and parallel in shape, compact and without awns. The grain is round, medium-sized, and pale red, with occasional variations in endosperm pigmentation. The adult plant height varies between 105 cm and 110 cm, with an average of 105 cm, and with moderate resistance to lodging. Heading growth stage occurred 5 days later than cultivar Maxwell and 8 to 10 days earlier than ‘Bicentenario INIA’ and ‘Kiron INIA’
