| Summary: | (weight), and NOR was more difficult to extract from peanut and field performance are correlated. and pod inoculations with A. flavus and A. parasiticus by HPLC (r = 0.83 and 0.95, respectively). Neither aflatoxin coloration was consistently apparent in shells of immature correlated with quantity of aflatoxin and NOR as determined cotyledons and testae. External fungal growth and coloration differences (P < 0.05) among lines when using immature and Differentiating breeding lines to eliminate highly dried seed. Although relative NOR production, determined for differential Aspet*llu,s flavus Links and A. parasiticus intercotyledonary cavity and the interfacial surface of laboratory conditions. Required environmental conditions of most susceptible followed by Starr, 55-437, and J-11, mutants that produce norsolorinic acid (NOR), an orange-red nor NOR were efficiently extracted from large samples of pods did not consistently reflect seed infection. Orange Orange coloration in seed challenged by NOR A. flavus and A. orange coloration, classified by color class, were highly orange coloration. Visual assessments of individual seed for parasiticus mutants was initially most prominent in the pigmented precursor of aflatoxin, showed significant pods. Mature pods varied from none to extensive, splotchy relative amount of aflatoxin contamination can be made relative ranking of the four checks showed Pronto to be the respectively, for production of NOR and aflatoxin. Comparing seed than aflatoxin. Visual classification of seed for six lines were found constantly having low NOR production. Spear growth and aflatoxin production under field and successfully using A. parasiticus NOR mutants. sufficient aflatoxin for analytical studies in any of the susceptible genotypes appears possible if laboratory assay temperature and moisture were not met for the production of The 38 lines that comprise 'Tamspan 90' peanut were studied the pod inoculations test, did not differ at P < 0.05, a the reactions of the lines in three tests for NOR production, three field experiments. Laboratory assays involving seed three-fold difference was observed among the 38 lines. The visually on the basis of orange-red pigment in the seed from |
