“…17 Intraspecic hybridization as a way of transferring desirable traits of related wild species (diseases resistance, abiotic stress resistance, higher yield etc.) to well-adapted and cultured crop C. abyssinica [85][86][87][88] was used by Du et al 89 Though, this approach is limited due to the sexual incompatibility between species that leads to low fertility of hybrids or the abortion of embryo at early development stages, such obstacles can be overcome by protoplast fusion and embryo rescue. 90,91 Hybrids of C. abyssinica, C. hispanica and C. kralikii can be obtained with or without embryo rescue.…”

“…The search for vegetable oils with suitable characteristics has been focused mainly on non-food species. Among the species that can potentially fulfil this purpose, crambe (Crambe abyssinica Hochst) is an important oilseed plant in the family Brassicaceae (Du, Huang, Guan, Li, & Huang, 2014) that deserves attention.…”

Estimates of genetic parameters and path analysis of crambe: An important oil plant for biofuel production

et al. 2020

Crambe is an oilseed plant producing oil that can be used for various industrial purposes, including the production of biofuel. It is a short-cycle, non-food plant that can be grown as a second crop following soybean or corn crops and using the same agricultural machinery. This work aimed to estimate genetic parameters and correlations between traits of genotypes grown for two years in seven locations in two Brazilian states. The cultivar FMS Brilhante and the lines CR 1101, CR 1102, CR 1105, CR 1202, CR 1303, and CR 1304 were used. The traits evaluated were grain yield (YD), plant height (PH), stem diameter (SD), first fruiting branch height (BH), 1,000-seed weight (SW), and number of branches (NB). The correlations between traits were identified from the phenotypic covariance matrix through path analysis. Based on the joint analysis, the interaction of genotypes x years x locations was observed. Expressive genetic variability was verified for all evaluated traits, which allows gains to be made with the selection of genotypes. High broad-sense heritabilities based on plot means were verified for YD, BH, and SW (82, 84 and 77%, respectively), which indicates the possibility of directly selecting them. SW and SD showed the greatest direct effects and strongest correlations with YD.

Divergence and estimates of genetic parameters in Crambe abyssinica: an oilseed plant for industrial uses

et al. 2018

Crambe’s breeding is still incipient, with few cultivars of interest. The aims of the present study were: i) to evaluate the divergence between 10 genotypes of crambe, through morphoagronomic and quality traits, using multivariate analyses; and ii) to estimate genetic parameters related to these traits. The trial was conducted in a greenhouse, and the experimental data were submitted to multivariate analysis and genetic evaluation. The genotypes differed significantly among them for plant height (PH), stem diameter (SD), number of branches per plant (NB), height of the first productive branch (HPB), mass of 1000 grains (M1000), grain yield (YIELD) and oil productivity (OIL). The experimental coefficient of variation revealed good precision (4.29 to 13.81%). The averages of YIELD (1936.94 kg/ha) and OIL (660.10 kg/ha) were high. The traits presented high estimates of broad-sense heritability on a mean genotype basis (h2 > 73.65). The cluster analysis revealed five clusters of genotypes. YIELD showed the greatest contribution (22.31%) to the diversity among the genotypes, followed by HPB, NB and SD. Genotypes 2 and 4 can be used as parents at future crosses, as they are promising in obtaining segregant populations.
