One hundred sixty‐two lines were used to detect genotypic diversity for 7 characters in Crambe abyssinica Hochst during 1970 and 1972. Lines used were from 2000 randomly selected out of PI247310 and PI279345, and reselected on the basis of their progeny performance in head row nurseries. The cultivars, ‘Prophet,’ ‘Meyer,’ and ‘Indy,’ were used as checks. Characters studied were seed yield, test wt, plant ht, % oil (measured gravimetrically and by nuclear magnetic resonance), days to bloom, and % glucosinolates. Statistical differences were detected among lines for all characters except % glucosinolates, based on individual year and combined analyses of variance. Broad sense heritability estimates ranged from .22–.88. Gains from selection, as a % of the mean for each character, were estimated at 1.13–14.11. Intercharacter relationships were analyzed by correlation. The ranges in variation for traits are considered limited for good progress from selection within the germplasm represented, but advances can be expected.
