Early selection for resistance to cacao witches’ broom in new parental combinations

چکیده
ABSTRACT Progenies from 69 crosses between parents obtained by recurrent selection for resistance and yield were inoculated with Moniliophthora perniciosa basidiospores. The symptoms evaluated compared those in the equally progenies of Catongo, SIC 23 SCA 6. Forty-three new did not differ statistically 6, while 10 better than this control. female that can be highlighted are (P4B x 6), (MA 16 (CEPEC 86 EET 75 clone. best male (CAB 214), 208) OC 67), which each other. This study proved existence gene combinations fathers mothers, occurrence additive effects dominant inheritance these factors, should allow clones higher levels durability.

Single nucleotide polymorphisms from Theobroma cacao expressed sequence tags associated with witches' broom disease in cacao.
In order to increase the efficiency of cacao tree resistance to witches' broom disease, which is caused by Moniliophthora perniciosa (Tricholomataceae), we looked for molecular markers that could help in the selection of resistant cacao genotypes. Among the different markers useful for developing marker-assisted selection, single nucleotide polymorphisms (SNPs) constitute the most common type o...

متن کاملGenetic and Biological Diversity of Trichoderma stromaticum, a Mycoparasite of the Cacao Witches'-Broom Pathogen.
ABSTRACT The witches'-broom disease, caused by the basidiomycete Crinipellis perniciosa, is the most limiting factor for cacao cultivation in Brazil. Trichoderma stromaticum is a mycoparasite of the witches'-broom pathogen of cacao that is currently being applied in the field to manage the disease in Bahia State, Brazil. In this work, molecular and traditional methods were used to study the gen...
متن کاملApoplastic and intracellular plant sugars regulate developmental transitions in witches’ broom disease of cacao
Witches' broom disease (WBD) of cacao differs from other typical hemibiotrophic plant diseases by its unusually long biotrophic phase. Plant carbon sources have been proposed to regulate WBD developmental transitions; however, nothing is known about their availability at the plant-fungus interface, the apoplastic fluid of cacao. Data are provided supporting a role for the dynamics of soluble ca...
متن کاملMoniliophthora perniciosa, the causal agent of witches' broom disease of cacao: what's new from this old foe?
UNLABELLED Moniliophthora perniciosa (=Crinipellis perniciosa) causes one of the three main fungal diseases of Theobroma cacao (cacao), the source of chocolate. This pathogen causes Witches' broom disease (WBD) and has brought about severe economic losses in all of the cacao-growing regions to which it has spread with yield reductions that range from 50 to 90%. Cacao production in South America...
