Milling Energy Polymorphism inHordeum spontaneumKoch in Israel and its Potential Utilization in Breeding for Malting Quality

摘要

AbstractVariation for grain milling energy inHordeum vulgareis associated with differences in grain size, shape and composition. Genetic polymorphisms within and between populations were found across the ecogeographical range ofHordeum spontaneumin Israel. Low milling energy estimates were positively correlated with and predictable by the aridity index. Milling energy inH. spontaneum, collected in Israel, ranged from the lowest values seen in making barley to twice the highest values seen in feed cultivars. It is concluded thatH. spontaneumelite genotypes could be effectively identified by milling energy for use in the breeding of new cultivars.
