dc.description.abstract As compared with other cereal grains , Sorghum bicolor shows very low levels ofprotein digestibility when exposed to proteolytic enzymes . Protein digestibility furtherdecreases when sorghum is cooked . It is speculated that low digestibility is the result ofextensive disulfide crosslinking in the - and -kafirins (storage proteins ) surroundingthe endosperm protein bodies . The degree of crosslinking increases as sorghum iscooked , causing the highly digestible -kafirins found at the interior of protein bodies tobe locked within a tightly bound capsule , inaccessible to digestive enzymes . In thisresearch project , two major QTLs were found to be associated with proteindigestibility ?one QTL unfavorably affecting digestibility and one QTL favorablyaffecting digestibility . By identifying the QTLs and the linked markers corresponding tothe highly digestible trait , breeders will be able to use marker -assisted selection toquickly and accurately identify highly digestible lines to advance in a breeding program . en_US
