Abstract
- Nutritious and functional foods from wheat have received great attention in recent years. Colored-grain wheat contains a large number of nutrients such as anthocyanins and hence the breeding is interesting. In this work, colored-grained wheat lines of mixed pollination of einkorn wheat (Triticum boeoticum, AA) and French rye (French Secale cereale, RR) were used as male parents and wheat line Y1642 (derived from common wheat and Agropyron elongatum, AABBDD) was used as the female parent. These colored wheat were used for diallel cross to study the segregation ratios of F1 colored grains. Results show that the color inheritance of purple-grained wheat follows a maternal inheritance pattern and that the blue-grained wheat expresses xenia in most cases. In some circumstances, the grains with different color shades appear in the same spike. Alimentos nutritivos e funcionais de trigo têm recebido grande atenção atualmente. Trigos de grãos coloridos contêm um grande número de nutrientes tais como antocianinas, e isso é interessante para melhoramento. Nesse trabalho, linhagens de trigo de grãos coloridos polinizadas com trigo ??? (Triticum boeoticum, AA) e centeio francês (French Secale cereale, RR) foram usadas como machos e a linhagem Y1642 (derivada de trigo comume??? Agropyron elongatum, AABBDD) como fêmea. Esses trigos coloridos foram usados em cruzamentos dialélicos para estudar segregação de grãos coloridos F1. A herança da cor púrpura de grãos seguiu um padrão materno e trigos de grãos azuis expressaram efeito de xênia, em muitos casos. Grãos com diferentes cores sombreadas apareceram na mesma espigueta.
