“…Thus, the larger the repeat number in the microsatellite DNA, the larger the number of alleles detected. Also it was reported that the dinucleotide repeat motif (GA) displayed high level of variation among the rice lines [38]. On the other hand, Sajib et al [31] reported no correlations between the number of alleles detected and the number of SSR repeats.…”

Fourteen rice lines and one cultivar were investigated for morphological traits and genetic diversity under normal and drought stress condition. Mean squares of years, environment and lines × environments were significant for all traits under observation, except for days to heading and grain yield/plant in years, days to heading in environment and days to heading and harvest index in lines × environments, respectively. The 10 SSR markers, covering seven chromosomes (1, 2, 4, 5, 6, 8 and 9) generated polymorphic alleles with sum of 72 alleles on seven chromosomes with 9 markers across the fifteen rice lines. Furthermore, genetic diversity values for all SSR markers varied from 0.94 to 1.00 with an average of 0.98. In addition, the PIC values ranged from 0.83 to 0.99 with an average value of 0.94. The promising lines of present investigation can be utilized in future plant breeding programs.

“…SSR markers were used to assess the genetic diversity level of local rice varieties (Kristamtini et al 2014;Thomson et al 2009) and the population structure (Suvi et al 2019), which are helpful as basic information for breeding. Parallel to breeding, genetic diversity information gained from local variety would benefit the sustainable conservation of plant genetic resources for food and agriculture (Hue et al 2018). This study aimed to evaluate the genetic diversity among 63 Indonesian local rice varieties and explore their genetic structure revealed by SSR markers complement agro-morphological information for better understanding and utilization as germplasm resources for breeding.…”

Indonesia's local rice varieties (Oryza sativa L.) have a wide range of diversity that can be valuable sources for crop improvement with molecular markers. This study investigated local rice varieties' genetic diversity and population structure using simple sequence repeat (SSR) markers. The SSR markers demonstrated their informativeness for genotypic characterization as represented by the gene diversity indices and polymorphic information content. The UPGMA dendrogram divided 63 varieties into two distinct clusters with different levels of sub-grouping and the tendency according to their origins, as supported by PCoA. In contrast, PCA of these varieties according to agro-morphological traits was scattered in all quadrants. Thus, DNA level variation analyzed by SSR seems to complement the phenotypic traits, which were not well structured and revealed significant genetic diversity among varieties, within, and among populations (P<0.01). The pattern of grouping structure analysis of total varieties into two subpopulations is similar to the dendrogram according to SSR markers but better resembles the pedigree information of the set local varieties. These findings have implied their importance in rice breeding for genetic improvement, maintenance, and management of local genetic resources in Indonesia.

“…However, SSR markers are codominant, highly polymorphic, informative, easily analyzed, and not expensive [14]. Several investigators used molecular markers in analyzing the quantitative traits in rice [15,16,17,18].…”

This investigation was conducted at Agriculture Research station, Sakha, Kafr El-sheikh, Egypt during 2019 and 2020 rice seasons to study genetic diversity, combining ability and photosynthetic parameters in rice. A line x tester model was used in this study where five rice varieties were crossed with three testers. Four primers were used to estimate the genetic diversity of the studied paternal lines and the values of major allele frequency ranged from 0.62 to 0.75 and averaging 0.69. Genetic diversity values ranged from 0.37 to 0.47 and averaging 0.42. The PIC values ranged from 0.43 to 0.61 and averaging 0.52. The GD dendrogram classified the studied rice genotypes into two main clusters: The first cluster included Giza 178 and Sakha 108, while the second cluster included the other genotypes. Genetic distance ranged from 0.147 to 0.886 and the highest genetic distance was observed between Giza 182 and Sakha 178. Highly significant differences were detected among genotypes and their partitions for all studied traits. The highest mean values were detected for the crosses Sakha 107 x Sakha 101 for earliness as well as Sakha 108 x Sakha 101 and Giza 182 x Giza 179 for grain yield plant -1 . The mean squares due to SCA were much higher than those of GCA for all studied traits, indicating that the studied traits were governed by non-additive gene action. The parent Sakha 107 expressed the highest significant and negative gca effects for days to 50% flowering. Parent Sakha 108 seemed to be the best general combiner for grain yield plant -1 . The most desirable SCA effects for days to 50% flowering were detected for the cross Sakha 108 x Sakha 101, while the cross Giza 182 x Giza 179 expressed the most desirable SCA effects for grain yield plant -1 . The most desirable mid-parent and better-parent heterosis values were detected for the cross Sakha 107 x Sakha 101 for days to 50% heading and the cross Sakha 108 x Sakha 101 for grain yield plant -1 . The cross Sakha 108 x Sakha 101 expressed the highest mean values of cuvette temperature, leaf diffusive, net assimilation rate and stomatal conductance, while the cross Sakha 107 x Giza 179 gave the best values for transpiration rate.
