Identification of new sources of resistance to Striga gesnerioides in cowpea Vigna unguiculata accessions
The parasitic weed, Striga gesnerioides, is a major threat to cowpea productivity throughout the savannas of West and Central Africa. The
identification of sources of S. gesnerioides resistance and their incorporation in ...
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 ...
Screening wild vigna species and cowpea (Vigna unguiculata) landraces for sources of resistance to striga gesnerioides
This chapter presents the results of a study conducted on the experimental field of the International Institute of Tropical Agriculture (IITA) in Minjibir, Kano State, Nigeria, during the planting seasons of 2012 and 2013 ...
Geographical distribution of traits and diversity in the world collection of pearl millet [Pennisetum glaucum (L.) R. Br., synonym: Cenchrus americanus (L.) Morrone] landraces conserved at the ICRISAT genebank
The genebank at ICRISAT conserves the
largest collection of 23,092 pearl millet germplasm
accessions originating in 52 countries. A total of 15,979
landraces originating in 34 countries and having geographic
coordinates ...
Surveys conducted to know the occurrence and distribution of diseases in chickpea and pigeonpea growing regions
For chickpea disease, a survey was conducted between November and January in four major chickpea growing states in central and southern parts of India viz. Andhra Pradesh, Karnataka and Maharashtra. For pigeonpea, survey ...
Study of expression pattern of defence genes in chickpea and pathogenicity causing genes in FOC through qPCR in resistant and susceptible cultivars grown under elevated CO2
Total RNA was extracted from root tissues of wilt infected and control chickpea seedlings of susceptible cv. JG 62 and resistant cv. WR 315 grown under ambient and elevated CO2 condition. cDNA was synthesized from total ...
Evaluation of host-plant resistance in chickpea by microbial treatment.
Three chickpea endophytes AUR-2, AUR-4 and ARR-10 were found effective against B. cinerea in vitro conditions in the previous screening. Under controlled conditions (1500 Lux light intensity, 12 h/day; 100% RH, 15±2 °C ...
Purification of secondary metabolites from 2 actinomycetes responsible for antagonistic activity against important fungal pathogens of chickpea and sorghum
In our previous study, a total of 137 actinomycetes, isolated from 25 different herbal vermi-composts, were characterized for their antagonistic potential against Macrophomina phaseolina (causes charcoal rot in sorghum and ...
Screening cowpea germplasm (cultivated and wild relatives) for aphid resistance
A total set of 376 entries including 374 mini-core accessions, 1 resistant check (TVu801) and 1 susceptible check (TVx 3236) were evaluated in screening cages at Kano and screen house at Cotonou for resistance to cowpea ...
Identification of suitable carrier material for plant growth-promoting (PGP) actinomycetes for long term storage
ICRISAT has identified 19 PGP actinomycetes, which were also demonstrated for their broad spectrum of PGP traits including biofortification, antagonistic and entomopathogenic traits on cereals such as rice, sorghum and ...
