Evaluation of morphological and biochemical traits of some genotypes of Ribes ‎biberistentii L. in Ilgene Chay watershed of Arasbaran forests

Reddish black berry fruit has a high antioxidant capacity and Iran is one of the most important centers of valuable plant diversity of this fruit. Therefore, in a study, the potential of this valuable medicinal plant in breeding, morphological, phytochemical and genetic diversity in Arasbaran region was investigated. The measured parameters included fruit morphological characteristics including fruit length, fruit weight and phytochemical properties of fruit such as soluble solids, phenolic compounds, flavonoids, anthocyanins, vitamin C, DPPH and peroxidase activity. The results of cluster analysis showed that the collected genotypes were divided into four main groups. In the first group, 9 genotypes (R 1; 18; 6; 9; 15; 7; 8; 13; 12) were present. The genotypes of this group had many similarities in terms of weight, fruit length and solids. In the second group, there were 3 genotypes (R 10; 3; 2) that were very similar in traits such as peroxidase and antioxidants. In the third group, 4 genotypes (R 14; 4; 17; 16) were present. The genotypes of this group were similar in phenol and anthocyanin traits. In the fourth group are 3 genotypes (R5; 11; 19), which are very similar in traits such as soluble solids and antioxidants, cluster analysis confirms the results.
