Abstract
The "random" method of oat breeding was assessed using 820 random lines from four crosses. Transgressive segregation was indicated for yield, maturity, height, bushel weight, and kernel weight, but it was not marked in the latter three traits. Correlations between yield and the above-listed traits were low, indicating that primary emphasis could be placed on productivity without detracting from selection effectiveness. It was concluded that the random method of oat breeding was efficient in breeding for productivity in an area with no serious disease problems. The weight of five panicles taken at random from standard rod-row plots was significantly correlated with plot yields, but the correlations were small and use of high panicle weight would probably not be effective in screening for high yield.
