Experimental studies in 1965 and 1966 indicated that double‐cross restored hybrid sugarbeets, Beta vulgaris L, have excellent potential for commercial use. In isolated seed plots, the female parental single crosses averaged about 100 g of double‐cross seed per plant. Forty‐six experimental double crosses showed favorable performance for gross sugar, root yield, sugar percentage, and quality in relation to that of two currently used commercial cultivars. A method for production of the double‐cross hybrid seed on a commercial scale is outlined.
