“…Dehgan and Webster (1979) postulated J. curcas as the most primitive form of the genus and that species in other sections evolved from J. curcas or other ancestral form with changes in growth habit and flower structures. J. curcas crosses readily with most of the species and is also known to form natural hybrid complexes (J. curcas-canascens; J. curcas-gossypifolia), which are associated with high degree of sterility (Dehgan and Webster 1979;Dehgan 1984;Prabakaran and Sujatha 1999). Hence, one must be cautious about the divergent material.…”

Jatropha curcas (Euphorbiaceae) is an oil-bearing species with multiple uses and considerable potential as a bioenergy crop. The present investigation has been undertaken to assess the extent of genetic diversity in a representative set of 42 accessions of J. curcas encompassing different crop growing regions in India along with a non-toxic genotype from Mexico as a prelude for utilization of promising and genetically divergent materials in the breeding programmes. Molecular polymorphism was 42.0% with 400 RAPD primers and 33.5% with 100 ISSR primers between accessions indicating modest levels of genetic variation in the Indian germplasm. The withinpopulation variation based on RAPD polymorphism was 64.0% and was on par with the inter-population variation. Polymorphic ISSR markers have been identified that could differentiate the Indian accessions from the Mexican genotype and two of them were converted to SCAR markers. The SCAR primer pair ISPJ1 amplified a 543 bp fragment in all the Indian populations, while ISPJ2 with a specific amplicon of 1,096 bp was specific to the Mexican genotype. Population-specific bands have been identified for the accession from Kerala (2 RAPD markers), Neemuch-1 from Rajasthan (1 each of RAPD and ISSR markers) and the non-toxic genotype from Mexico (17 RAPD and 4 ISSR markers), which serve as diagnostic markers in genotyping. The study indicates an immediate need for widening the genetic base of J. curcas germplasm through introduction of accessions with broader geographical background.

“…The main mission was to increase the yield by developing high-yielding variety through genetic using classical and advanced methods.Under this mission maximum work appears to be inappropriate and similar experiments were repeated a specific number of times without generating new knowledge. Few natural hybrid complexes have been reported like J. curcas-canascens from Mexico [20], J. integerrima-hastata from Cuba and West Indian islands [21] and J. curcas-gossypiifolia (J. tanjorensis) from India [22]. The present status of improvement work is very limited and both intra-and interspecific hybridization work initiated to create more variability in selected parents.…”

It is almost 45 years since the mission Jatropha started for the development of high-yielding strain for commercial exploitation as a source of biofuel plant. A massive amount of literature has been accumulated on almost all aspects of Jatropha. It is now very important to evaluate the results related to the selection/development of novel strains. No preferable strains have been developed either through intra-and inter-specific hybridization or induced mutagenesis. Literature survey indicates that the quantum of work towards the development of new variety under the Jatropha mission is very negligible in comparison to other works. Maximum activities are not in synchronization with the exact mission of the project. It is now very important to choose the correct path to escalate Jatropha to industrial status within a reasonable time. Breeders may intelligently think about the selection of the best available strain, periodical pruning, and induced mutagenesis for commercial exploitation before doing further experiments with Jatropha. It is now high time to prepare need-based planning considering ongoing and on-coming research areas.

“…Cymose inflorescence with coinflorescence, monoecious unisexual and bisexual, medium sized green with pale pink tinged flowers, 8 yellow stamens arranged in a single layer, highly sterile pollen. Fruit not seen [59] J. tanjorensis is popular as a natural remedy against malaria infection and hypertension in some parts of Nigeria, however there is dearth in scientific validation of these claims [60]. Edo people in Nigeria consumed the leaves as a vegetable and known as catholic vegetable [61].…”

Medicinal and metabolite compounds from jatropha species are important in protective against various diseases like hypertensive, antimalarial, dyscrasia, anemia, vertigo, ysphonia ,neoplasia, inflammation, ulcers etc. In present study of Chloroform and metanolic extracts of stem and stembark of various Jatropha species was carried out using standard in vitro models. The metabolic activity was evaluated in vitro by using three different species. The result of the study depends of concentration of the metanolic and Chloroform extracts of the stem bark of Jatropha species. This study will provide suitable opportunities for further investigation to verify these activities in vivo.
