Diversity analysis of indica rice accessions (Oryza sativa L.) using morphological and SSR markers
Morphological and molecular characterization of twenty six landraces rice and four high yielding rice accessions were studied to observe genetic diversity assessment and identification of superior genotypes for crop improvement program. Fourteen morphological and twenty seven DNA based molecular markers, simple sequence repeat (SSR), were used extensively to carry out this study. A wide range o...
متن کاملGENETIC DIVERSITY ASSESSMENT OF RICE (Oryza sativa L.) GERMPLASM USING SSR MARKERS
Rice Diversity PIC SSR marker Diversity at molecular level among thirty rice genotypes, selected based on earliness and morphometric diversity was evaluated through five SSR markers associated with days to heading. Three primers viz., RM147, RM167 and RM215 showed polymorphism for growth duration related traits. A total of 17 alleles were detected among the 30 rice genotypes with an average of ...
متن کاملMetabolic prediction of important agronomic traits in hybrid rice (Oryza sativa L.).
Hybrid crops have contributed greatly to improvements in global food and fodder production over the past several decades. Nevertheless, the growing population and changing climate have produced food crises and energy shortages. Breeding new elite hybrid varieties is currently an urgent task, but present breeding procedures are time-consuming and labour-intensive. In this study, parental metabol...
متن کاملSeed dormancy and seedling vigour as influenced by planting time environment and date of harvest in rice (Oryza sativa L.)
Seed dormancy is a genetically inherited trait whose intensity is modified by the environment during seed development and maturation. In order to study the effect of harvest time on the seed quality and optimum time of sowing to obtain good quality seeds, freshly threshed seeds of ten diverse rice genotypes harvested from six environments were evaluated for seed dormancy and seedling vigour ind...
متن کاملAssociation Mapping for Important Agronomic Traits in Core Collection of Rice (Oryza sativa L.) with SSR Markers
Mining elite genes within rice landraces is of importance for the improvement of cultivated rice. An association mapping for 12 agronomic traits was carried out using a core collection of rice consisting of 150 landraces (Panel 1) with 274 simple sequence repeat (SSR) markers, and the mapping results were further verified using a Chinese national rice micro-core collection (Panel 2) and a colle...
