Although cassava is a major food crop, its scientific breeding began only recently compared with other crops. Significant progress has been achieved, particularly in Asia where cassava is used mainly for industrial processes and no major biotic constraints affect its productivity. Cassava breedin...

Plantain and banana (Musa spp. L.) polyploid hybrids have been obtained after interspecific hybridisation and ploidy manipulations (i.e., interploidy crosses). The identification of promising hybrids for cultivar release requires their field testing to assess agronomic performance. The potential ...

L'hybridation et les manipulations ploodiques, c'est-a-dire les croisements interploidiques, ont permis d'obtenir les hybrides polyploides des plantains et des banaiers (Musa spp. L.). L'identification des hybrides prometteurs susceptibles de donner lieu aux cultivars necessite un essai au champ ...

Bananas and plantains (Musa spp.) are the most important tropical fruit crops. They form an integral component of the farming systems in the humid agroecological zones of the tropics. A broad array of applied cell and molecular techniques are increasingly being used worldwide to facilitate and en...

The cowpea breeding programmes are reviewed and achievements at two major centres of cowpea research, i.e. IITA (Nigeria) and IARI (India), are summarized. Earlyand extra early genotypes are always photoperiod-insensitive, medium maturity varieties could be sensitive or neutral today length, whil...

Current efforts to produce improved genotypes of plantain and banana (Musa spp.) depend on crossing female-fertile clones with accessions that produce viable pollen. Musa accessions (168) were screened for production of viable pollen based on staining with acetocarmine glycerol jelly. Diploid hyb...

Seed set in triploid Musa spp. L. is very low due to high levels of sterility. This makes cross breeding of plantain and banana difficult. Nonetheless, several triploid plantain and banana cultivars produce seeds after hand pollination with diploid parents. This paper reports results about the pa...

We attempted to determine ploidy level in the gametophyte and the sporophyte of Musa using pollen and chloroplast characteristics, respectively. In the gametophyte, interploidy differences accounted for 63.8 % of the genetic variance for pollen diameter and 87.5% for pollen stainability, the rema...
