GENERAL-CHARACTERISTICS AND MILLING PERFORMANCE OF CLUB WHEAT VS. SOFT WHITE WINTER-WHEAT

Seventy-five club and 125 soft white winter (SWW) wheats, grown under different growing conditions, were examined to identify the difference s between club and SWW wheats in grain characteristics and milling per formance. Club wheat was significantly lower in test weight and 1,000- kernel weight and significantly higher in near-infrared spectroscopy h ardness score than was SWW wheat. There were no differences in protein or ash content. Club wheat exhibited better milling performance as in dicated by higher total flour yield and milling score than did SWW whe at. Growing conditions had strong influence on grain characteristics a nd milling performance in both classes of wheat. Variety had a large e ffect on SWW wheat but not on club wheat. In general, club wheat exhib ited better stability over growing conditions than did SWW wheat. A po sitive correlation (r = 0.408) between test weight and flour yield was found in club wheat but not in SWW wheat.
