Table 4. Effect of bunch position (static pressure) on ripening period <strong>and</strong> weight loss<br />

(%) of Musa fruit*.<br />

Bunch position Days to ripe Weight lost (%)<br />

Top 11.0 18.3<br />

Middle 11.0 18.7<br />

Bottom 10.0 19.7<br />

CV (%) 8.6 6.2<br />

*Average of six bunches for each genotype.<br />

<strong>and</strong> plantain l<strong>and</strong>races, particularly when the fruits are to be processed green. The<br />

l<strong>and</strong>race plantains <strong>and</strong> cooking bananas were firmer than the plantain hybrids. The<br />

texture of the hybrid fruit was more like a banana than a plantain <strong>and</strong> this may cause<br />

difficulties in the distribution of the fresh fruit. Improvement of the mechanical strength<br />

of the hybrids calls for breeder’s attention to enable the fruit to withst<strong>and</strong> the rigours of<br />

the distribution system in Africa. Market acceptance of the new Musa breeds in view of<br />

their weaker pulp also needs to be investigated.<br />
