Conduct Participatory Variety Selection (PVS) trials of promising varieties across target agroecologies in Ethiopia, Tanzania, Uganda and Kenya
PVS trials were established and evaluated in Ethiopia, Kenya, and Uganda. In Tanzania for example, six varieties advanced from HOPE 1 were evaluated in 4 districts, each district with 15 trials. All the six candidate ...
Groundnut lines that combine several desirable traits into single genotype to meet the needs of the farmer, consumer and industry.
Single-seed descent, pedigree, and backcross methods of breeding are used to improve the target traits. Selection in segregating populations are enabled by (a) markers for three traits, resistance to rust and late leaf ...
Virulence profiling of F. udum isolates to understand the current status of race/pathotypes prevalent in major pigeonpea growing areas in India
Out of 111 isolates, total 67 isolates were selected for virulence profiling based on geographical location, pathogenicity, cultural and morphological characters. The F. udum isolates represented 38 districts belonging to ...
Quantification of Foc colonization through qPCR in resistant and susceptible cultivars grown under elevated CO2
The chickpea seedlings of susceptible cv. JG 62 and resistant cv. WR 315 were grown in open top chambers at different CO2 concentrations [ambient (~380 ppm) and elevated ( 550 ppm and 700 ppm). Seven day old seedlings were ...
Development of segregating populations for heat stress tolerance in chickpea
Breeding materials for heat tolerance were at different stages of development. A total of 4 F1s, 5 F2 populations, 3 F4 populations, and 16 F5 populations were advanced to next generation in normal season 2015-16 at ...
RNA-seq based transcriptome profiling, identification and validation of heat stress responsive genes in chickpea
Six contrasting heat responsive (tolerant - ICCV 92944, ICC 1356, ICC 15614 and sensitive - ICC 5912, ICC 4567, ICC 10685) genotypes were selected for the study. Heat stress was imposed using growth chamber facility, ...
Multilocation progeny tests of Diversified Dual-Purpose Populaiton for yield and adaptation
Sorghum plays an important role in the diets and economies of the people of Nigeria, where the average per capita annual consumption among smallholder farmers is more than 75 kg/person. However, since 2009, there has been ...
Construction of Saturated Genetic Map
The first version of genetic map was constructed using the T-population (Tifrunner × GT-C20) with 239 mapped loci which was then improved to 378 marker loci. In the present study, genotyping data was generated for additional ...
Identification and Training of Smallholder seed producers
Efficient farmer groups with a biases on women headed, were chosen to produce QDS or community based seed. Representatives from the groups together with other progressive farmers were then selected and trained on the ...
Repeat assessment of CSSL of peanut (introgression of AixAd into cultivated Fleur11) in Lysimeters and LeasyScan, and analysis of the multiyear data
Transpiration efficiency (TE) measurements were carried out in a lysimetric system, which has been described in many papers by the group (see Vadez et al., 2014). In short, groundnut plants were grown in 1.2-m length and ...
