“…Therefore, it may be suggested that separation of these two cultivars from the others may be the result of their adaptation to the environmental and cultivation practices available in the south of the country. A sim-ilar result has also been revealed by RAPD analysis of the same genotypes reported earlier (Samaee et al, 2003).…”

“…Therefore, they may be considered as synonyms or mislabeled accessions as a result of morphological difficulties. The previous studies on Iranian olive cultivars have also revealed such misnaming (Hosseini-Mazinani et al, 2004;Samaee et al, 2003).…”

“…The total olive production was 60,000 tons in 2005 (Zeinanloo, 2006). Although a large number of olive accessions are growing in Iran, there have been few limited reports on morphological, cytogenetic, and molecular characteristics of these accessions (Hosseini-Mazinani et al, 2004;Omrani-Sabbaghi et al, 2007;Samaee et al, 2003;Sheidai et al, 2007).…”

Numerous olive cultivars are cultivated in Iran, mainly in the north. Ninety-two accessions belonging to 10 main olive cultivars were screened by 13 microsatellite markers revealing high genetic variability both within and between cultivars. In total, 72 alleles were detected with a mean number of 5.5 alleles per locus. Twenty-four unique allelic patterns were observed, whereas six genotypes showed 15 unique alleles. Heterozygosity ranged from 0.00 to 0.98, whereas the mean number of discrimination power and polymorphic information content were 0.55 and 0.54, respectively. The combination of 5 simple sequence repeat markers made discrimination of 84% of all accessions included in the study possible. The existence of homonyms, synonyms, or mislabeling as well as intracultivar polymorphism was revealed by allele differences between accessions of the same denomination. The phenogram showed variability among as well as between some cultivars, but most accessions with the same generic names were grouped together.

“…All these traits under study are reliable for selection in genetic improvement of the chilli genotypes. Traits whose expressions are environmentally dependent may not be reliable descriptors for morphological characterization (Samaee et al, 2003;Pandey et al, 2008). However, in this study, the proportion of genetic contribution to the overall phenotypic expression of most of the traits was very high.…”

Increased productivity of dry chilli with appreciable fruit quality is the present need in major growing areas to promote export from our country. The present investigation was undertaken to identify important selection indices, and to analyze the genetic divergence of collected germplasm for identification of diverse parents for spice chilli hybridization program. Different components of genetic variability for 15 growth and yield component traits were determined employing 45 genotypes evaluated in autumn-winter season of 2015-16 in Randomized Block Design with three replications. High GCV and PCV values were recorded for all the characters except days to 50% flowering, days to ripe fruit maturity from anthesis and 1000 seed weight. The proportion of genetic contribution to the overall phenotypic expression of most of the traits was very high. Both heritability and genetic advance was high for all the characters under study except days to ripe fruit maturity from anthesis, revealing additive genetic control of characters. Selection would be most useful for the improvement of these traits. Dry fruit yield/plant was found positively and significantly correlated with all the traits except days to 50% flowering and days to ripe fruit maturity from anthesis. Path coefficient analysis indicated that the maximum direct effect on dry fruit yield/plant was through ripe fruit yield/plant followed by dry fruit weight. From the combing study of correlation and path coefficient, the characters, namely ripe fruit yield/plant and dry fruit weight were the most important selection criteria, emphasis should be given on such traits while imposing selection for amenability in dry fruit yield of chilli. Based on the determination of divergence all the genotypes were grouped into 7 clusters. However, random grouping pattern of genotypes was observed indicating that geographical diversity and genetic divergence were unrelated. The intra-and inter-cluster distance among the genotypes depicted that crossing between the genotypes belonging in Cluster I and VII or Cluster III and VII will be expected to give high heterotic response in F 1 generation. The character fruit length contributed the maximum towards genetic divergence followed by fruit diameter, fruits/plant and plant spread (N-S). Based on D 2 Statistics, PCA and mean performance, six genitors Beldanga, BCCH Sel-4, G-4, BCC-30, BCC-25, and Srinagar possessed the optimum combination of all variables and were identified as most promising donor parents in dry chilli hybridization programme with a view to develop promising hybrids/improved lines.

“…At present, the old commercial olive orchards are located mainly in the north of Iran and more than 85 % of olive production belongs to these regions (Noormohammadi et al, 2007). A large number of olive accessions are growing in Iran; therefore, many workers have reported on morphological or molecular characteristics of these accessions (Samaee et al, 2003;Hosseini-Mazinani et al, 2004, Omrani-Sabbaghi et al, 2007Sheidai et al, 2007;Noormohammadi et al, 2012;Dastkar et al, 2013). The genetic diversity could be an important resource for the development of modern olive culture towards typical olive oil and fresh products (Hegazi et al, 2012).…”

Iran is known as one of the origins of olive in the world with many different olive cultivars, mainly in the north. Eighty eight accessions belong to 4 main olive cultivars were investigated by 21 morphological characters and 11 ISSR markers. Analyses of morphological characters revealed the existence of high genetic variability among cultivars. Based on both morphological and ISSR cluster analyses, 88 accessions were grouped in five distinct clusters. The ISSR primers produced 77 polymorphic bands. AMOVA showed significant difference in both between and within olive cultivars. The highest and lowest coefficient of Nei’s genetic distance was observed in ‘Mari’ and ‘Shengeh’ (0.105) and ‘Zard’ and ‘Rowghani’ (0.061), respectively. In both morphological and ISSR data analyses, ‘Mari’ showed the highest homogeneity. The olive cultivars were not clustered based on their geographical origin.
