Rosa damascena perfume rose has a considerable place in Morocco. The essential oil, hydrolate (rose water) and dried buds produced in Kalâa Mgouna are intended for export. However, local varieties are not identified. Hence, the objective of our research into the identification of morphological variability by studying 15 qualitative and quantitative characteristics related to leaf, spine and flower at eight localities along the valley of roses. The present study has demonstrated the existence of a great morphological variability within the Kalâa Mgouna’s perfume rose. The characters associated with leaves and spines drive this variability. The PCA analysis identified four morphotypes; the morphotype I whose stems are unarmed, the morphotype II characterized by broad leaves and moderately spiny stems, the morphotype III having stems bearing long spines and whose petals are wider. Finally, the morphotype IV characterized by very thorny stems, leaves of reduced size and whose petals are wider.
大马士革玫瑰香水在摩洛哥占有相当大的地位。在kal阿Mgouna生产的精油、水合物(玫瑰水)和干花蕾用于出口。然而，当地品种没有被确定。因此，我们研究的目的是通过对沿玫瑰谷8个地点的叶、棘和花的15个定性和定量特征进行研究，以确定形态变异。目前的研究已经证明了在kal a Mgouna香水玫瑰中存在着巨大的形态变异。与叶和刺相关的性状驱动这种变异。主成分分析鉴定出四种形态;I型茎无武装，II型叶宽，茎有中等多刺，III型茎有长刺，花瓣较宽。最后是IV型，茎多刺，叶小，花瓣宽。

A set of germplasm of ninety accessions of rice (Oryza sativa L.) were collected in Egypt to assess genetic biodiversity. Using SSR markers some specific quantitative trait loci associated with tolerance to abiotic stress, resistance to blast disease and enhance the grain yield were found. Phylogenic data was collected. Eight primers (RM 315, RM 318, RM 166, RM 302, RM 201, RM 234, RM 526 and RM 144) showed different polymorphism frequencies. The polymorphism was nearly 80 %. The size of detected fragments ranged from 105–325 bp. A total of 186 bands were scored from the amplification products with the ten SSR primers. Genetic diversity analyses were conducted on the basis of the scores with 176 unique bands. Phylogenic trees for the fifteen rice accessions from each group and subgroup were established according to the molecular data and based on ten SSRs. A marked genetic diversity was observed in the five groups and the origin genotypes from the five groups were (Sakha 101, IR 03N137, IR 83142-12, IR 87856-10-AJY-1-B, HHZ 12-Y4-DT1-Y2 and IR 1552), respectively which showed higher layers of diversity and hence can be used as donors for the effective conservation, utilization and providing favorable genes and valuable germplasm in rice breeding.
