“…Jatropha succeeds in crossing with other species in its genus, such as J. integerrima Jacq. (Laosatit et al 2017;Fukuhara et al 2016). Inter-speci c hybridization can help widen the genetic base of Jatropha, thereby making it more widely distributed.…”

Reducing plant spacing and pruning Jatropha hybrids may increase yield. The study aimed to investigate the effect of reduced plant spacing on yield productivity, assess pruning tolerance, and discover the relationship between yield and growth traits of Jatropha hybrids. Fourteen Jatropha hybrid genotypes evaluated yield with narrow and standard plant spacing for two years. After the first year, the Jatropha hybrid plants were hard-pruned and allowed to regrow in the second year. It found that although narrower plant spacing might reduce Jatropha hybrid growth and yield per plant, increasing plant density by reducing plant spacing could increase fruit yield, seed yield, and oil yield by up to 65.46%, 64.73%, and 63.25%, respectively, when compared to standard spacing. Furthermore, hard pruning could improve the growth of Jatropha hybrids, and pruning tolerance varied between genotypes. Under narrow spacing, KUJL110 and KUJL70 had the highest yields after pruning, and KUJL110, KUJL30, and KUJL23 had the highest pruning tolerance index (PTI). It discovered a correlation (ranging from 0.49** to 0.86**) between yield traits and plant height, canopy width, and the number of secondary branches. Additionally, a correlation (ranging from 0.51** to 0.83**) was found between oil content and shelling, as well as 100 seed weight. As a result, these traits may serve as an indirect tool for selecting Jatropha genotypes with high-yield traits.

“…curcas L. However, pre- and post-fertilization barriers affect the hybridization process [10]. Laosatit et al [10] reported on embryo abortion, a post-fertilization barrier, which was overcome by ovule culture. Sterility of F 1 hybrids is also very common in intergeneric hybridization [11].…”

Jatropha curcas L. (2n = 2× = 22) is increasingly attracting attention in the biodiesel industry for its oil. However, the cultivation of J. curcas L. is faced with numerous challenges unlike the cultivation of Ricinus communis L. (2n = 2× = 20), a closely related species. The generation of an intergeneric hybrid between J. curcas L. and R. communis L. was investigated. Intergeneric hybrids were produced by hand crossing. Immature embryos were rescued, in vitro, from the hybrid seeds and cultured on an enriched Murashige and Skoog (MS) medium for a month. The plantlets produced were grown in sterile peat moss in plastic pots and covered with polyethylene for 30 days, after which they were transferred into cement potted soil. The hybridity and the genuineness of the hybrids were successfully confirmed using randomly amplified polymorphic DNA (RAPD) markers. The number of branches, stem diameter, and leaf size of the F1 hybrids were similar to those of J. curcas L. while the plant height was similar to that of R. communis L. Young hybrids were treated with various concentrations (0%, 0.3%, 0.4%, and 0.5%) of colchicine to induce polyploids. The calli (JR6) treated with 0.3% colchicine recorded the highest tetraploid cell percentage (38.89%). A high tetraploid cell percentage (>50%) is significant in overcoming the problem of sterility after hybridization.

“…Jatropha curcas is a monoecious species with unisexual flowers (Montes and Melchinger, 2016); xenogamic (Divakara et al, 2010;de Argollo Marques et al, 2013); self-compatible (Chang-Wei et al, 2007;Brasileiro et al, 2012), and diploid (2n = 2x = 22), as well as most congeners species (Carvalho et al, 2008;Sasikala and Paramathma, 2010;Marinho et al, 2018). These traits allow crosses between Jatropha species, although with limited success due to either pre-or post-zygotic barriers (Moreira et al, 2013), which can be overcome using in vitro embryo rescue technique (Laosatit et al, 2017). However, several successful crosses have been reported, for instance, between J. curcas and J. integerrima, aiming at shorter plants, higher seed oil yield, resistance to diseases, woody biomass, etc (Sujatha and Prabakaran, 2003;Parthiban et al, 2009;One et al, 2014).…”

Genome composition and pollen viability of Jatropha (Euphorbiaceae) interspecific hybrids by Genomic In Situ Hybridization (GISH)

Interspecific hybridization is required for the development of Jatropha curcas L. improved cultivars, due to its narrow genetic basis. The present study aimed to analyze the parental genomic composition of F 1 and BC 1 F 1 generations derived from interspecific crosses (J. curcas/J. integerrima and J. curcas/J. multifida) by GISH (Genomic In Situ Hybridization), and the meiotic index and pollen viability of F 1 hybrids. In F 1 cells from both hybrids, 11 chromosomes of each parental was observed, as expected, but chromosome rearrangement events could be detected using rDNA chromosome markers, suggesting unbalanced cells. In the BC 1 F 1 , both hybrids had 22 chromosomes, suggesting that only n = 11 gametes were viable in the next generation. However, GISH allowed the identification of three and two alien chromosomes in J. curcas//J. integerrima and J. curcas//J. multifida BC 1 F 1 hybrids, respectively, suggesting a preferential transmission of J. curcas chromosomes for both hybrids. Pollen viability in F 1 hybrids derived from J. curcas/J. integerrima crosses were higher (82-83%) than those found for J. curcas/J. multifida (68%), showing post-meiotic problems in these last hybrids, with dyads, triads, polyads, and micronuclei as post-meiosis results. The here presented cytogenetic characterization of interspecific hybrids and their backcross progenies can contribute to the selection of the best genotypes for future assisted breeding of J. curcas.
