Study of Diversity in Some Moroccan Population of Saffron (Crocus sativus L.) | Chapter 05 | Research and Development in Agricultural Sciences Vol. 1
To study Moroccan saffron germplasm
variability relating to different agro-morphological and phenological traits,
969 saffron corms (accessions) were collected from thirteen different sites
located in traditional saffron area of Taliouine-Taznakht. The study confirmed
a wide range of phenotypic variability within and between populations. The variance
analysis revealed that the mother corm weight (MCW), taken as covariant, has
significant effect on all studied traits. The difference within and between
origins (Provenances) was highly significant for all traits, which showed
highly significant correlation. The flowers number (NF) as well as the number
of daughter corms weighing above 7 g per plant (NDC≥7) turned out to be the
most determinant parameters of saffron yield. The produced FN per corm varied
from 1 to 9 with an average of 2.2 flowers. P1 population recorded a flowering
rate of 65.5% with a maximum average of NF (2). Stigmat length (SL), which is
an important yield trait, showed wide variation between origins from 32 to 38
mm. The mean stigma dry weight (DSW) varied from 4.2 to 6.2 mg with a maximum
of 7.1 mg per flower recorded in P1. The PCA revealed 5 homogeneous main groups
inside the studied populations. The first one was monoorganogenic and consisted
of P1 population only, a group characterized by high values of MCW, NF, NDC≥7
and DSW. This study confirms as well a noticeable influence of corm origin on
saffron yield, explained by the genotypic profile and/or the epigenetic effects
of the different origins. These results proved a variability which should be
useful to the selection program aiming the improvement of saffron productivity
in Morocco.
