A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Prevalence and Socioeconomic Impact of Striga (Striga hermonthica) in Sorghum Producing Areas of East and West Hararghe Zones, Oromia, Ethiopia

International Journal of Agronomy, 2022
Striga is one of the biotic constraints limiting the production and productivity of sorghum in tropical Africa, particularly in Ethiopia. A field survey was conducted in the eastern and western Hararghe zones in six districts in the 2019 cropping season ...

Genome-Wide Association Studies for Striga asiatica Resistance in Tropical Maize

International Journal of Genomics, 2021
Striga asiatica L. is a parasitic weed in cereal crops including maize leading to tremendous yield losses up to 100% under severe infestation. The available S.

Quantitative‐genetic parameters of sorghum growth under striga infestation in Mali and Kenya [PDF]

Plant Breeding, 2001
AbstractTo estimate quantitative‐genetic parameters of sorghum for resistance to the hemi‐parasitic weed striga [Striga hermonthica (Del.) Benth.] and for agronomic traits, 36 diallel F2 populations and their nine parental lines were evaluated under severe striga infestation at two locations each in Mali and Kenya. Location means for grain yield ranged

Assessment of sorghum anthracnose (Colletotrichum sublineolum P. Henn.) intensity and its association with biophysical factors in Western and Southwestern regions of Ethiopia

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Ethiopia is Africa's second‐largest sorghum producer [Sorghum bicolor (L.) moench]. Despite these potentials, the production and productivity of sorghum yield remained low due to many agricultural factors. Among the factors, sorghum anthracnose caused by Colletotrichum sublineolum is one of the main fungal diseases substantially reducing ...

Identification of QTLs Controlling Resistance/Tolerance to Striga hermonthica in an Extra-Early Maturing Yellow Maize Population

Agronomy, 2020
Striga hermonthica parasitism is a major constraint to maize production in sub-Saharan Africa with yield losses reaching 100% under severe infestation. The application of marker-assisted selection is highly promising for accelerating breeding for Striga ...

Molecular insights into volatile organic compound sensing and signaling in plants

The Plant Journal, Volume 125, Issue 6, March 2026.
SUMMARY Plants interact with their surrounding environment through the perception of a vast and structurally diverse array of volatile organic compounds (VOCs); however, the molecular mechanisms involved remain mostly unknown. Despite the large number of VOCs emitted and perceived by plants, only a small number of phylogenetically distinct, but often ...

Performance of cowpea varieties under Striga gesnerioides (Willd.) Vatke infestation using biplot analysis [PDF]

Euphytica, 2017
Striga gesnerioides (Willd) Vatke, is a major destructive parasitic weed of cowpea (Vigna unguiculata (L.) Walp.) which causes substantial yield reduction in West and Central Africa. The presence of different virulent races within the parasite population contributes to significant genotype × environment interaction, and complicates breeding for durable

The Complexity of Multidimensional Learning in Agriculture

Econometrica, Volume 94, Issue 2, Page 465-503, March 2026.
Studies on agricultural technology adoption often focus on one input, practice, or package, which is analytically useful, but may overlook the complexities involved with multidimensional learning needed for a lot of agricultural decisions. In Kenya, we study farmers' dynamic learning (from oneself and others) and adoption decisions over six seasons ...
