Maize (Zea mays L.) stalk rot, caused primarily by the soil-borne fungal pathogen Fusarium spp., reduces maize quality and yield worldwide. This study was undertaken to develop and utilize a rapid continuous injection inoculation technique to evaluate maize inbred lines for resistance to Fusarium spp. under field conditions, which could facilitate the identification and development of new sources of host resistance to manage the disease. Continuous injection inoculation is a rapid, stable, and simple method that can evaluate the resistance of maize inbred lines to Fusarium stalk rot (FSR) within 20 days. To verify the feasibility and reliability of inoculation method, Fusarium graminearum, F. proliferatum, and F. subglutinans were isolated, identified, and inoculated into maize at the six-leaf stage (V6) by a veterinary adjustable bottle continuous vaccination syringe. Our results showed that out of a total of 97 inbred maize lines, six (6.2%) showed high resistance to maize stalk rot, 20 showed resistance (20.6%), 32 were susceptible (33.0%), and 39 were very susceptible (40.2%). Based on simple sequence repeat (SSR) markers, an analysis of molecular variance indicated a significant correlation between population of the inbred maize line and resistance to FSR (P = 0.001). Overall, this study provided a systematic, rapid, stable, and simple identification method for maize inbred lines resistant to FSR in the field. At the same time, this method was also suitable for genetic diversity analysis of maize inbred lines resistant to FSR.

ABSTRACT Allozyme balances serve as markers of quantitative behavior of electrophoretically distinguishable alleles. By the use of ADH Set I allozyme balances, it is demonstrated that all Adh1-S/Adh1-F individuals from more than 20 diverse S/F families exhibit a reciprocal correlation between Adh1 quantitative behavior in two maize organs: the scutellum and primary root. Within an electrophoretic mobility class, the Adh1 allele that is relatively underexpressed in the scutellum is relatively overexpressed in the primary root, and vice versa. Segregation tests prove that this "reciprocal effect" is the property of a cis-acting site that is closely linked to or within the Adh1 structural gene, and it is not affected by diverse genetic backgrounds. Immunological and [3H]-leucine incorporation experiments establish that Adh1 quantitative variants differ in ADH1·ADH1 synthetic rates in the anaerobic primary root. The reciprocal-effect phenomenon suggests that the cis-acting loci controlling Adh1 quantitative expression in each respective organ are at least in close proximity, or may share common DNA sequences. We discuss the possibility that the reciprocal-effect locus is a regulatory component of the Adh1 cistron.
