Genetic diversity analyzed by microsatellite markers among rice (Oryza sativa L.) genotypes with different adaptations to saline soils

Cross-genera amplification of informative microsatellite markers from common bean and lentil for the assessment of genetic diversity in pigeonpea

“…High levels of polymorphism associated with microsatellites are expected because of the unique mechanism responsible for generating microsatellite allelic diversity by replication slippage (Tautz and Renz, 1984;Tautz, 1989) rather than by simple mutations or insertions/ deletions. Microsatellites have been used in many crop plants for detection of genetic diversity (Zeng et al, 2006;Stepien et al, 2004). Ford et al (2002) reported the use of Pisum sativum specific microsatellite primers to assess genetic relationships among pea cultivars.…”

Assessment of Genetic Diversity of NIFOR Oil Palm Main Breeding Parent Genotypes Using Microsatellite Markers

“…It is the case of the 5 oil palms including Ufuma dura (AD3) and tenera (T5), Aba dura (AD5), Opobo dura (AD4), and Umuabi tenera (T6) recently introduced in the NIFOR Main Breeding Programme. However, the speculation of adaptive genetic variants as proposed by Zeng et al [68] cannot be precluded because the geographical origin of the palms, ecology, agroclimatic conditions, pedology, and ethnical behaviour of local farmers could justify the presence of private alleles. All the parents are derived from palms originally selected on account of their high yields or good fruit composition from small oil palm groves at Aba, Calabar, Ufuma, Umuabi, and Opobo, which form part of a very large contiguous population constituting the oil palm belt of Nigeria.…”

Genetical and Molecular Studies on Salinity and Drought Tolerance in Rice (Oryza Sativa L.)

“…This result is consistent with that at Sajib et al (2012) who reported greatly variations in PIC values for all tested SSR loci (from 0.14 to 0.71 with an average of 0.48). Higher averages of PIC values (0.57) were reported by Zeng et al (2004) and (0.707) by Ram et al, (2007). According to Anderson et al (1993), there were seven highly informative markers (PIC > 0.50), one informative marker (50 < PIC < 0.25) and no slightly informative markers (PIC < 0.25).…”

“…El-Malky et al (2007) reported the ability of SSR makers to divide the genotypes into two groups, one included the Indica genotypes and the other included the Japonica genotypes. Also, Zeng et al (2004) found that, all genotypes clearly grouped into two major branches in the dendrogram with less than 10% similarity based on Jaccard similarity index, one branch represented the subspecies Japonica rice and the other branch represented the subspecies Indica or the hybrids between Japonica rice and Indica rice.…”
