Seven Iranian and foreign cultivars of rice were crossed in a half-diallel. Parents with F2-generations were transplanted in a randomized complete blocks design with 3 replications and evaluated for length to breath ratio of paddy and brown rice, head rice and crust, grain yield, percent of head rice and broken rice, amylose content, gelatinization temperature and gel consistency. The ANOVA tab...

Molecular marker assisted selection (MAS) has been touted as a means to improve the efficiency and speed of plant selection programs. The most widespread use of MAS to date is to assist backcrossing of major genes into already proven, elite cultivars. Markers can aid selection for target alleles that are not easily assayed in individual plants, minimize linkage drag around the target gene, and ...

quantitative traits locus for milk production traits has been described on centromeric end of bovine chromosome 14. reports name the acyl coa: diacylglycerol acyltransferase (dgat1) gene as a potential candidate gene with dinucleotide substitution (aa to gc) in exon viii which causes the change of lysine to alanine in amino acid (k232a).the aim of the present study was to estimate the frequency...

In order to identify QTLs controlling agronomically traits, landrace Tarom and rice Tarom mutant were crossed. SSR, ISSR, iPBS and IRAP markers were amplified in 250 F2 individuals to prepare the linkage map. Number of tillers, 100 grain weight, number of filled grains, number of unfilled grains, plant height, panicle length, number of branches, stem diameter, grain length, grain width, grain s...

Pigeonpea is an important pulse crop grown predominantly in the tropical and sub-tropical regions of the world. Although pigeonpea growing area has considerably increased, yield has remained stagnant for the last six decades mainly due to the exposure of the crop to various biotic and abiotic constraints. In addition, low level of genetic variability and limited genomic resources have been seri...

DNA information has the potential to generate value for each sector of the beef-cattle industry. The value distribution among sectors (breeding, commercial, feedlot, processing) will differ depending on marketing. The more descendants an animal produces, themore valuable each unit of genetic improvement becomes. Therefore, the value of using DNA testing to increase the accuracy of selection and...

The use of appropriate selection methods are important to increase yield in breeding programs. Utilization of selection indices is one of the most effective method for selection of superior genotypes to improve the complex traits such as seed yield. In order to evaluate the efficiency of different selection methods, 63 families of two F3 populations derived from inter-specific hybridization of ...

Grain yield is a quantitative trait, which determined by several agronomic traits. Unfortunately, there little information about the genetics behind components in US rice cultivars. The objectives of present study were to (1) conduct QTL identify chromosome (chr. hereafter) regions associated with traits two U.S.-developed cultivars and (2) candidate genes major related Four evaluated summer 20...
