“…In India, Tripathi et al (2013) found that the average production of 113 genotypes of jatropha in the second and third year after planting ranged from 26.1 kg ha -1 to 763.8 kg ha -1 , demonstrating great variability between genotypes and low productivity due to crop is not genetically improved. High yields were obtained by Santoso and Purwoko (2016), in Indonesia, when effect of pruning was tested on jatropha plants.…”

Information of jatropha genotypes yield are scarce, but necessary to promote the crop establishment, so it is very important for the commercial planting of this crop. Thus, this study aimed to evaluate the canopy growth and productivity of three jatropha genotypes. The experimental design was a randomized block, with 15 treatments, three replications and five plants per plot. The jatropha genotypes were selected because they have some special characteristics: (CNPAE-107 -small size, CNPAE-133 -productive and CNPAE-169 -seeds without toxicity) obtained in the Germplasm Bank of Embrapa Agroenergy, Brasília, DF, Brazil. The data were collected for five cycles of production. We evaluated: grain yield; height and canopy volume. Treatments differ in all characteristics. Jatropha grain yield has been growing along the first four years of evaluation, however, in the fifth year production was lower when compared to the fourth year. The most productive genotype was CNPAE-133 (2123.8 Kg ha -1 year), followed by CNPAE-107 genotypes (2076.5 Kg ha -1 year) and CNPAE-169 (913 Kg ha -1 year), the highest yields were obtained at 3.7 years.

ResumoInformações sobre a produção de genótipos de pinhão-manso por longo período são escassas, mas extremamente necessárias para fomentar o estabelecimento da cultura, assim, é de grande importância realizar pesquisas que testem o desempenho produtivo dessa espécie por longo período de tempo. Dessa forma, objetivou-se avaliar o crescimento da copa e a produtividade de três genótipos de pinhão-manso. O delineamento experimental utilizado foi em blocos ao acaso, constituído de 15 tratamentos, com três repetições e cinco plantas por parcela. Os tratamentos consistiram de genótipos de pinhão-manso selecionados por terem alguma característica especial: (CNPAE-107 -porte baixo, CNPAE-133 -produtivo e CNPAE-169 -sementes sem toxicidade) obtidos no banco de germoplasma da Embrapa Agroenergia. Os dados foram coletados durante cinco ciclos de produção. Foram avaliadas: produção de grãos; altura e volume de copa. As plantas diferiram em todas as características avaliadas. A produção de grãos do pinhão-manso foi crescente ao longo dos quatro primeiros anos de avaliação, porém, no quinto ano a produção foi menor quando comparada ao quarto ano. O genótipo mais produtivo foi o CNPAE-133 (2123,8 kg ha -1 ano), seguido pelos genótipos CNPAE-107 (2076,5 kg ha -1 ano) e CNPAE-169 (913 kg ha -1 ano), cujas maiores produtividades foram registradas aos 3,7 anos.

“…Modern techniques have accelerated characterization of J. curcas germplasm at molecular level (Singh et al, 2010;Xu et al, 2012) and even whole genome sequencing (Sato et al, 2010). However, information regarding the extent and pattern of genetic variation in J. curcas population is limited barring a few recent studies (Kaushik et al, 2007;Rao et al, 2008;Gairola et al, 2011;Tripathi et al, 2013;Brasileiro et al, 2013). Therefore, genetic and correlation studies among the seed traits were carried out in candidate plus trees of J. curcas selected from a wide geographical range in three Eastern Indian states aiming at utilization in oil yield improvement.…”

Jatropha curcas has received considerable attention from researchers as a potential source of nonedible vegetable oil which is eminently suitable for production of liquid bio fuel, meeting international standards. For any tree improvement and breeding programme, study of variation among the populations is prerequisite as it helps in the detection of relative performance of various traits of economic value. 28 candidate plus trees were selected from the states of Jharkhand, West Bengal and Bihar in Eastern India. Nine seed parameters were measured and their genetic values and correlation was calculated to serve as base information for further improvement and breeding of J. curcas in Eastern India. Significant genetic differences exist in all the seed characteristics among the different candidate plus trees of J. curcas. Positive direct effect of seed width and protein content was observed on seed oil content. Indirect effect of seed traits via seed width was positive. Thus, seed width can be taken as a criterion for selecting trees with good oil yield. The variations in most studied parameters were under genotypic control among seed sources. Highest coefficient of variation was found for seed oil content emphasizing the need of wide scale screening and selection of superior genotypes to capture the existing variability.
