Breeding Maize for a Bioeconomy: A Literature Survey Examining Harvest Index and Stover Yield and Their Relationship to Grain Yield

摘要: The use of maize (Zea mays L.) stover as a feed-stock for cellulosic biofuels production will create demand hybrids with greater yield. It is expected that grain yield remain the most critical trait and continue to drive hybrid sales, requiring any increases in be made without sacrificing potential. objective this review was determine relationship between yield, harvest index, illuminate potential increasing both through breeding. In contrast what has been observed other crops, gains over time U.S. Corn Belt have accompanied by Where recurrent selection on successful, also increased while index relatively stable. opposite situation tropical germplasm, where associated constant biomass We expect increase along resulting future capable producing more food biofeedstock energy production. If breeders pursue we found no evidence suggest breeding necessarily reduce rate gain
