Selection of morphological traits to improve forage characteristics of Setaria sphacelata grown in Florida

摘要: A genetically diverse population of Setaria sphacelata was developed at Gainesville, Florida by intercrossing the cultivars 'Narok', 'Ka- zungula' and 'Solander' a local persistent popu- lation. To determine heritability traits that may improve setaria as forage plant in Florida, progeny intercrossed underwent two cycles selection for inflorescence number one cycle leaf width. The selected populations, together with introductions, were evaluated morphological characters, yield quality field experiments close- wide-spaced plants. Increase not obtained but resulted decreased height, length, yield, width, leafiness. Leaf width increased associated leafiness whole-plant crude protein content. results sug- gest good prospects
