Zusammenfassung: | The loquat fruit has a very important commercial value due to its benefits
for human health. However, there is very limited scientific research on this
species in Morocco. In this regard, a set of 35 genotypes was collected from
the Zegzel valley (Berkane). The phenotypic variability was evaluated using
nine traits related to fruit and leaf. The results revealed a coefficient of
variation ranging from 13.02 to 42.21%, implying a large phenotypic
variation in Moroccan loquat, especially for the characteristics associated
to the fruit shape. Regarding the multiple correspondence analysis, the
first two axes explained 62.57% of the total variance. The major traits that
made it possible to distinguish between the genotypes were those related to
fruit size. Therefore, the Mekerkba genotype in the Zegzel region is not a
single variety, but rather genotypes with a round fruit shape. In addition,
the 35 genotypes studied were divided into three main groups regardless of
their geographical origin. The results indicate that the geographical
proximity did not play an important role in the structure of genotypes,
implying a weak adaptation of the genotypes to the environment. The findings
of this study could be used in conventional breeding and in situ
conservation programs for Moroccan loquat. |
