WorldVeg takes the chili challenge!
Hot or not? Only a taste […]
WorldVeg South Asia staff Devender Pal Kaur, Ramashray Dubey and Souradeep Acharjee discovered first-hand the complexities of the chili value chain during a study trip from 13-14 November 2017 in Andhra Pradesh, India.
Surveys were conducted in 2014 and 2015 in Southern and Northern Benin, respectively, to identify the viruses infecting peppers (Capsicum spp.). The samples were screened by ELISA for cucumber mosaic virus (CMV), pepper veinal mottle virus (PVMV), potato virus Y (PVY) and tomato yellow leaf curl virus (TYLCV). A generic reverse transcription PCR (RT-PCR) was used to test for the presence of poleroviruses. ELISA tests confirmed the prevalence of all viruses, while the RT-PCR detected pepper vein yellows virus (PeVYV) which is reported for the first time in Benin. A further, divergent polerovirus isolate was detected from a single pepper sample originating from southern Benin. Screening of samples collected from solanaceous plants during virus surveys in Mali (conducted in 2009) also detected this divergent polerovirus isolate in two samples from African eggplants. The complete genome sequence was obtained from the Mali isolate using transcriptome sequencing and by conventional Sanger sequencing of overlapping RT-PCR products. Based on the sequence characteristics of this isolate we propose a new polerovirus species, African eggplant yellowing virus (AeYV).
This project designs alternative options for insect pest management and will set the stage for partners to promote and popularize these options.
Quantitative trait loci (QTLs) for plant height (PHT) and other yield-related traits including number of fruits per plant (NFP), ten fruits weight (TFW), fruit length (FL), fruit width (FW), total fruit weight (ToFW) and pericarp thickness (PT) were mapped in intraspecific advanced recombinant inbred line (RIL) populations of pepper.
AVRDC is a partner in a new € 6.9 million initiative funded by the European Commission to focus on the cataloguing and characterization of global potato, tomato, pepper and eggplant genetic resources
Taste, color, texture: all are important when introducing a new variety to the market.
