to study the population structure of gibberella fujikuroi species complex, the causal agent of rice foot rot, samples were taken from different rice growing regions of guilan province in 2004. among fourty-one isolates recovered from different cultivars; three isolates did not produce microconidial chain. in order to study the sexual fertility and determine the mating type as well as mating pop...

This study was conducted to determine the combining ability and heritability of rice grain quality traits. Some grain quality traits such as grain length, grain width, milled grain length, milled grain width, length to width ratio, milled rice recovery, head rice recovery, amylose and gel consistency were analyzed using a full diallel mating design in Malaysian rice varieties. This study was co...

The combining ability analysis using Line × Tester model was conducted in chickpea to know the general and specific combining ability of the distingushing parents and their crosses, respectively and to select best material for further breeding programme and generation advanceme- nt. Two genetically diverse testers viz., JAKI-9218 and ICCV-2 as females and 8 males viz., HC-5, ICC-506, PKV Harita...

We describe the genetic and molecular analysis of the first non-Mendelian mutants of Chlamydomonas reinhardtii resistant to myxothiazol, an inhibitor of the respiratory cytochrome bc1 complex. Using a set of seven oligonucleotide probes, restriction fragments containing the mitochondrial cytochrome b (cyt b) gene from C. reinhardtii were isolated from a mitochondrial DNA library. This gene is l...

The objective of this study was to assess the ability experimental advanced breeding clones as parental genotypes transmit agronomic and quality traits their progenies in programs. A half diallel set crosses (excluding reciprocals) with six parents assayed field trials for three years; four were Solanumtuberosum subsp. tuberosum cultivars, two them that included genes from S. andigenum immunity...
