“…High or moderate F-values for variation suggest that selection for these characteristics might be successful. The maximum erucic acid content of 60.1 % equals levels found for C. abyssinica (Earle et al, 1966;Pokorny & Zeman, 1967;Nieschlag & Wolff, 1971;Mastebroek et al, 1994). The low contents of linoleic and linolenic acid in the seed oil of C. hispanica, compared to C. abyssinica, offer good prospects for its application as a lubricant or refrigerant.…”

“…abyssinica have been released : 'Prophet', 'Indy', 'Meyer' (Lessman, 1975), 'BelAnn' and 'BelEnzian' (Campbell et al ., 1986) . However, further improvement is restricted due to a lack of variation within C. abyssinica for important agricultural characteristics, such as erucic acid content and total glucosinolate content (Papathanasiou et al ., 1966 ;Lessman & Meier, 1972 ;Mastebroek et al ., 1994). C. hispanica might be useful as a new source of variation .…”

In order to assess the potential of Crambe hispanica, either in breeding programmes of C . abyssinica or as an oilseed crop in itself, 36 accessions of C. hispanica (29 of var. hispanica and 7 of var. glabrata) were grown in a greenhouse and evaluated for morphological characteristics, earliness, plant habit, seed characteristics and fatty acid composition . Four lines of C. abyssinica were included for reference . The 29 accessions of var . hispanica showed significant variation for all observed characteristics . Besides morphological characteristics, large variation was found for earliness, number of primary branches, seed yield, 1000 seed weight and volume, and linoleic, linolenic and erucic acid content . Morphological characteristics, earliness and plant habit did not show any high correlations with seed characteristics or fatty acid composition, except for seed hull (pericarp) mottling, which was related to a high oil and erucic acid content . The seven accessions of var. glabrata showed little variation . The large genetic variation in combination with promising figures for several characteristics, found in C . hispanica, may be useful in breeding programmes of the oilseed crop C . abyssinica, for which the available genetic variation is limited : Prospects of selection for high-erucic acid genotypes are discussed . Compared to C. abyssinica, both botanical varieties of C. hispanica are characterized by a cordate shape of the basal leaves, lack of seed retention and a lower DNA content. Plants of var. glabrata differed from var. hispanica in a sparsely hispid upper leaf surface and round stems and branches covered with a waxy layer . These clear differences and lack of success in intercrossing both varieties of C. hispanica strongly suggest that their taxonomic classification should be reconsidered .

“…the superior progenies in different locations or years, with expectations that they were superior due to the genetic characteristics instead of the environmental factors. Mastebroek et al (1994) obtained 15% of genetic gain for grain yield with the selection of lines of crambe from Europe. Lessman (1975) obtained expected genetic gains of 1.13% for oil content, 14.11% for grain weight, and 6.69% for grain yield with the selection of individual plants.…”

“…The objectives of the crambe breeding program are to increase grain yield, grain oil content, and erucic acid in the oil as well as to reduce glucosinolate content (antinutritional factors) and promote tolerance to diseases caused by Alternaria and Sclerotinia (Knights 2002). However, the breeding programs efficiency has been hampered by the lack of genetic variability (Mastebroek et al 1994, Lessman and Meier 1972, Papathanasiou et al 1966.…”
