Expression of different mechanisms of resistance to insects in groundnut under field conditions
Host plant resistance is an important component of pest management, and information on contribution of different mechanisms of resistance is important for developing cultivars with resistance to the target pests. Therfore, ...
Translational Genomics in Agriculture: Some Examples in Grain Legumes
Recent advances in genomics and associated disciplines like
bioinformatics havemade it possible to develop genomic resources, such as large-scale sequence data for any crop species.While these datasets have been proven ...
Identification of quantitative trait loci for yield and yield related traits in groundnut (Arachis hypogaea L.) under different water regimes in Niger and Senegal
Yield under drought stress is a highly complex trait with large influence to even a minor fluctuation in the environmental conditions. Genomics-assisted breeding holds great promise for improving such complex traits more ...
Assessing the genetic diversity of 48 groundnut (Arachis hypogaea L.) genotypes in the Guinea savanna agro-ecology of Ghana, using microsatellite-based markers
Groundnut (Arachis hypogaea L.) is the most important grain legume in Ghana. However, its production
is constrained by a myriad of biotic and abiotic stresses which necessitate the development and use of
superior varieties ...
Uncommon occurrence ratios of aflatoxin B1, B 2, G 1, and G 2 in maize and groundnuts from Malawi
We report an unusual aflatoxin profile in maize and groundnuts from Malawi, with aflatoxin G1 found routinely at equal or even higher levels than aflatoxin B1. Aflatoxin B1 (AFB1) ratio in a contaminated sample is generally ...
Validation of markers linked to late leaf spot and rust resistance, and selection of superior genotypes among diverse recombinant inbred lines and backcross lines in peanut (Arachis hypogaea L.)
Recombinant inbred lines (RILs) from four populations involving cultivated varieties, and backcross lines from three populations involving cultivated varieties and synthetic tetraploids (developed from wild diploids) were ...
Identification of groundnut (Arachis hypogaea) SSR markers suitable for multiple resistance traits QTL mapping in African germplasm
Background
This study aimed to identify and select informative Simple Sequence Repeat (SSR) markers that may be linked to resistance to important groundnut diseases such as Early Leaf Spot, Groundnut Rosette Disease, rust ...
Screening of groundnut interspecific derivatives for resistance to Sclerotium rolfsii
Sclerotium rolfsii is a major constraint for production in most of the groundnut growing areas in India
inflicting 28-30 per cent yield losses annually. Irrigated groundnut grown in the post-rainy and summer
seasons in ...
Yield loss Modeling for late Leafspot and Rust in Groundnut
Late leaf spot and rust diseases occur together and cause considerable yield loss in groundnut.
Cultivation of resistant varieties is the best strategy to stabilize productivity under disease epidemics.
Several varieties ...
Identification of groundnut genotypes resistant to iron deficiency chlorosis
Groundnut (Arachis hypogaea L.) is the second most
important oilseed in India, which is mainly grown in states like
Gujarat, Andhra Pradesh, Karnataka, Tamil Nadu and
Maharashtra. More than one-third of the soils in ...
