Crearea noilor surse cu rezistenţă complexă a porumbului la agenţii patogenii de tăciune, putregaiul tulpinei şi a ştiuletelui

Abstract

In topcross schemes using testers geneticly susceptible tu pathogens U.maydis, S.holci-sorghi f.zeae, Fusarium ssp. and F.moniliforme were studied 12 lines of maize from different groups of maturity under artificial infection. Among these inbrends create AI 12-38-1C, AI 12-40-3D , AI 12-50-1o2 were determined as complexly resistance and possesing good general combining ability for grain yield. During 1992-2002 were tested 150 lines of maize and ≥1500 are involved in the same testing models.
