✦ Synopsis
Ten interspecific crosses of Avena sativa L . X A . sterilis L . were used to study associations of groat protein percentage with selected seed and agronomic traits . Each cross was grown in a replicated experiment, and the genetic material consisted of parents and F2 -derived lines grown in the F 4 generation .
No close associations were found between groat protein percentage and plant height, heading date, or 10-groat weight . Individual crosses did show significant correlations, but none of the 3 traits was sufficiently associated with groat protein generally so as to be beneficial or inhibitory to combining high groat-protein percentage with the maturity, plant height, and 10-groat weight appropriate for good agronomic cultivars of oats .
High groat-protein percentage was closely associated with abscission spikelet separation and jointed awn, both of which are A . sterilis traits . Shattering and dark seed color (A . sterilis traits) were also associated with high groat protein percentage, but kernel pubescence was not. Only a few segregates within each cross were A . sativa type for all 5 of the seed traits, but when A . sativa types from all crosses were grouped together, there was a large range for groat-protein percentages .
