Journal Article 1995

Autor: Crouch, J.H. Lewis, B.G. Lydiate, D.J. Mithen, R.F.

Restriction Fragment Length Polymorphisms (RFLPs) were used to study the genetic diversity within and between accessions of 'wild' and cultivated B. rapa. Two of the wild accessions were likely to be escapes from cultivation because of their geographical origins (Argentina and California). The na...

This study examined the potential of somaclonal variation for the improvement of plantain. Approximately 500 somaclones each of ‘Agbagba’ (False Horn plantain) and ‘Bise Egome’ (French plantain) were field evaluated for their agronomic performance and response to the black Sigatoka disease. The m...

The triploid genome of plantain (Musa spp., AA group) has been considered intractable to genetic improvement because of the production of putatively homogeneous 2n (= 3.r) gametes. Plantain breeding schemes have been based on the hybridization of 2n megaspores from the triploid plantain and haplo...

The world economy experienced significant growth and transformation, with increases in productivity, product quality, and export base diversification in the 1990s. These advances were mainly driven by the growth of traditional agricultural and industrial sectors, including the natural resource-ba...

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

Plantain-derived tetraploid hybrids are routinely crossed In Musa breeding programmes with diploid Musa accessions for the efficient generation of putative triploid hybrid seed. However, natural open pollination of these same tetraploid hybrids also consistently generates viable seed. The mean ge...

A permanent mapping population of rice consisting of 65 non-idealized chromosome segment substitution lines (denoted as CSSL1 to CSSL65) and 82 donor parent chromosome segments (denoted as M1 to M82) was used to identify QTL with additive effects for two rice quality traits, area of chalky endosp...

Progress in the breeding of plantain and banana has been restricted by the complex genetic structure and behaviour of cultivated polyploid Musa. Genetic improvement has been hindered due to the large amount of space required for growth and maintenance of plant populations, in addition to the long...
