Journal Article 1998

Autor: Crouch, J.H. Vuylsteke, D.R. Ortiz, R.

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...

Genome size variation occurs within and across generations in Musa spp., which reduces the predictive accuracy of parental performance on progeny value for yield and other traits with complex inheritance. Parental selection through progeny testing of prospective parents is required to achieve fur...

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...

Molecular genetic techniques may have a wide range of applications for improving the efficiency of Musa breeding and conservation. These range from analysis of genetic behaviour and structure, germplasm characterization and marker assisted selection. Restriction fragment length polymorphism (RFLP...

Genetic diversity amongst 76 plantain landraces has been studied using RAPD analysis at two levels of intensity and compared with groupings based on phenotypic indices and morphotype. There was a good correlation (R2=0.78) between estimates of genetic diversity based on 76 RAPD bands and 164 RAPD...

Autor: Tenkouano, A. Crouch, J.H. Ortiz, R.

Parent–offspring regression has often been used for the estimation of breeding value and narrow-sense heritability in experimental populations, particularly for diploid species with regular disomic inheritance. With polysomic inheritance, estimates of heritability based on parent–offspring regres...

Crop biotechnology seems to be in its infancy in Africa, some national researchers are well trained in this area but lack of funding from their national governments does not allow them take advantage of their knowledge and professional skills. Among the agro-biotechnology tools, tissue culture ra...
