Agronomic and Physiological Indices for Reproductive Stage Heat Stress Tolerance in Green Super Rice
Optimum growing temperature is necessary for maximum yield-potential in any crop. The global atmospheric changing more rapidly and irregularly every year. High at the flowering/reproductive stage rice causes partial to complete pollen sterility, resulting significant reduction grain yield. Green Super Rice (GSR) an effort develop elite type that can withstand multiple environmental stresses mai...
A study was conducted on genetics of some important agronomic traits (number of productive tillers per hill, plant height (cm), panicle length (cm), number of spikelets per panicle and 100-grain weight) in rice during 2012-13. Two lines were crossed with five testers in line × tester fashion to produce 10 F1 hybrids. Analysis of variance revealed significant differences among genotyp...

In order to evaluate genetic diversity of grain yield, nitrogen uptake efficiency and selecting superior varieties, a factorial experiment with the based on Complete Blocks design with four replications was carried out in Saatlo agricultural research station, six corn genotypes (single cross 301,370,540,700,701 and Back cross) and three amounts of nitrogen fertilizer (urea) (27 as a control, 11...
The present research aims to study the association and allelic diversity of linked microsatellite markers to grain quality QTLs of 84 exotic rice genotypes. To this end, 9 microsatellite markers (RM540, RM539, RM587, RM527, RM216, RM467, RM3188, RM246, RM5461) were used in which a total of 61 alleles were identified with a mean of 6 alleles per locus. The polymorphism information content (PIC) ...
Breeding of rice for drought tolerance requires proper evaluation and analysis of genetic diversity in breeding populations related to drought tolerance. In order to identify indices for tolerant and sensitive rice genotypes to drought stress, an experiment with 59 genotypes of rice was conducted based of a complete block design with three replications in non-stressed (flooding) and stressed co...
Rice is a worldwide important grain crop, which is considered as the main food and most important source of providing protein and calories for people in the world. Correlation analysis of different traits and yield components with the grain yield is a very important issue in the selection and breeding programs of genotypes. The experiment was performed in the form of completely randomized ...
Aflatoxin contamination and its relationship to storage length in stored maize and rice in Liaoning Province, northeastern China, was investigated. Aflatoxins in 110 samples collected from an area of 14.68million km covering storage length from 1 yr to over 10 yr were determined by high-performance liquid chromatography with fluorescence detection. The results showed that almost all samples col...
The extreme stress tolerance and high nutritional value of sand rice (Agriophyllum squarrosum) make it attractive for use as an alternative crop in response to concerns about ongoing climate change and future food security. However, a lack of genetic information hinders understanding of the mechanisms underpinning the morphological and physiological adaptations of sand rice. In the present stud...
Six Iranian rice cultivars (Binam, Domsiyah, Shahpasand, Sepidrud, Khazar and Valed 46) were crossed in 1989 in the Iranian Rice Research Institute in Rasht, Iran in a full-diallel design. The F1 progenies together with parents were transplanted in a CRBD in the 5 x 0.75 m plots at plant density of 25 x 25 cm (60 plantlets per plot) in 3 replications. Part of this research was published in 1994...
