Relationship between meiotic behaviour and fertility in backcross-1 derivatives of the [( × ) × ] trispecies hybrid.

Wild cotton species are an important source of desirable genes for genetic improvement of cultivated cotton Linnaeus, 1763. For the success of such an improvement, chromosome pairings and recombinations in hybrids are fundamental. The wild African species Hutchinson & Lee, 1958 could be used as donor of the desirable trait of fiber fineness.

Artemisia annua and Artemisia afra tea infusions vs. artesunate-amodiaquine (ASAQ) in treating Plasmodium falciparum malaria in a large scale, double blind, randomized clinical trial.

Background And Objective: Prior small-scale clinical trials showed that Artemisia annua and Artemisia afra infusions, decoctions, capsules, or tablets were low cost, easy to use, and efficient in curing malaria infections. In a larger-scale trial in Kalima district, Democratic Republic of Congo, we aimed to show A. annua and/or A.

Effect of Artemisia annua and Artemisia afra tea infusions on schistosomiasis in a large clinical trial.

Background And Objective: Schistosomiasis (bilharzia), a serious neglected tropical disease affecting millions, has few cost-effective treatments, so two Artemisia wormwood species, A. annua and A. afra, were compared with the current standard praziquantel (PZQ) treatment in an 800 patient clinical trial, August-November of 2015.

Digestibility of solvent-treated Jatropha curcas kernel by broiler chickens in Senegal.

Jatropha curcas is a drought-resistant shrub belonging to the Euphorbiaceae family. The kernel contains approximately 60 % lipid in dry matter, and the meal obtained after oil extraction could be an exceptional source of protein for family poultry farming, in the absence of curcin and, especially, some diterpene derivatives phorbol esters that are partially lipophilic. The nutrient digestibility of J.

Insects associated with Jatropha curcas Linn. (Euphorbiaceae) in west Niger.

Jatropha curcas has been introduced into Niger since 2004 by International Crops Research Institute for the Semi-Arid Tropics (ICRISAT). This plant is cultivated for its oil, which can be used as a Biofuel. Through direct and indirect insect collection methods, an inventory of the insect associated with J.

Phaseolus immature embryo rescue technology.

Predominant among the production constraints of the common bean Phaseolus vulgaris are infestation of Ascochyta blight, Bean Golden Mosaic virus (BGMV), and Bean Fly. Interbreeding with Phaseolus -coccineus L. and/or Phaseolus polyanthus Greenm has been shown to provide P.
