Mokoumbi, Y.D.Sie, M.Vodouhe, R.S.N'dri, B.Toulou, B.Ogunpayo, O.Ahanchédé, A.[Assessing phenotypic diversity of interspecific rice varieties using agro-morphological charcterization]Assessing phenotypic diversity of interspecific rice varieties using agro-morphological charcterization

Thermal stress and in particular heat during anthesis causes sterility in rice inflorescences. Rice spikelets open in the morning and close a few hours later. Genotypic variation in the time of day of anthesis is considered an escape mechanism from thermal stress, but little is known on its depen...

A morphological diversity study was conducted on African rice gall midge Orseolia oryzivora Harris & Gagné and two other African species, Orseolia bonzii Harris and Orseolia nwanzei Harris & Nwilene, sp. n. Morphological differences between adult and immature stages of the three species are sligh...

Seedling vigor is important to help ensure good crop establishment. In direct-seeded rice, this is particularly relevant when soil conditions are marginal. In Asia, about one third of the area of rainfed rice is situated on unfavorable soils, many of which are low in plant available P. In such en...

This Highlight reviews 34 papers that deal with interventions aimed at reducing negative impacts of irrigating with Arsenic (As) rich water. These studies show that there are six broad groups of interventions: deficit irrigation, soil fertilization, growing crops other than paddy, switching to As...

Viral diseases in crop plants constitute a major obstacle to food security in the developing world. Subsistence crops, including cassava, sweetpotato, potato, banana, papaya, common bean, rice and maize are often infected with RNA and/or DNA viruses that cannot be controlled with pesticides. Henc...

The future security of the supply of rice for food in Africa depends on improving the level of local production to achieve self-sufficiency. In order to cope with the existing gap between production and actual demand, combining a high level of rice blast tolerance and a high-yield potential is ne...
