Demarcation of informative chromosomes in tropical sweet corn inbred lines using microsatellite DNA markers
A study of genetic variation among 10 pairs of chromosomes extracted from 13 tropical sweet corn inbred lines, using 99 microsatellite markers, revealed a wide range of genetic diversity. Allelic richness and the number of effective alleles per chromosome ranged from 2.78 to 4.33 and 1.96 to 3.47, respectively, with respective mean values of 3.62 and 2.73. According to the Shannon's information...
متن کاملGenetic diversity analysis of recombinant inbred lines of rice (Oryza sativa L.) using microsatellite markers
Estimation of genetic diversity is an important factor in germplasm conservation and characterization. In rice breeding programs, genetic diversity information on specific regions of genome can be very useful for the application of marker assisted selection (MAS) and for gene mapping. A total of 152 rice lines were considered for breeding programs using microsatellites (SSR) technique. The tota...
متن کاملStudy on Combining Ability and Gene Effects Estimation in Some Sweet Corn Inbred Lines (Zea mays L. var saccarata) by Line × Tester Method
In breeding programs determination of gene effects and general and specific combining ability for screening of test crosses is necessary. In order to estimate the genetic variance components and the general and specific combining ability of sweet corn lines, an experiment was conducted using 8 sweet corn S6 inbred lines (including 4 maternal and 4 paternal lines) by line × tester mating design ...
متن کاملAnalysis of the genetic diversity of super sweet corn inbred lines using SSR and SSAP markers.
In this study, we compared the efficiency of simple sequence repeat (SSR) and sequence specific amplified polymorphism (SSAP) markers for analyzing genetic diversity, genetic relationships, and population structure of 87 super sweet corn inbred lines from different origins. SSR markers showed higher average gene diversity and Shannon's information index than SSAP markers. To assess genetic rela...
متن کاملMapping QTLs related to Zn and Fe concentrations in bread wheat (Triticum aestivum) grain using microsatellite markers
Mineral nutrient malnutrition, particularly deficiency in zinc and iron, afflicts over 3 billion people worldwide. Biofortification of food crops is the best approach for conciliating the micronutrient deficiencies. Understanding the genetic basis of their accumulation is the preconditions for enhancing of these micronutrients. In our study, a mapping population of a set of 118 recombinant inbr...
