Studies were conducted on 20 rice hybrids with checks to assess the genetic variability, heritability and correlation among the genotypes for fifteen grain quality characters and grain yield. Seeds collected from the thirteen hybrids and check varieties were used for grain quality analysis. To assess the cooking qualities, a total of 30 unbroken milled grains were measured for their length and ...

Two-dimensional phase field simulations were performed of grain growth in highly textured materials with equal fractions of 2 texture components, denoted as α and β grains, and assuming 2 values of the grain boundary energies, namely σlow for the boundaries between grains of a different texture component and σhigh for boundaries between grains of a similar orientation, resulting in microstructu...

Genetic relatedness among Indian farmers’ rice varieties were assessed using 24 distinct rice microsatellite markers. The 41 rice genotypes studied included 14 improved varieties and 27 landraces collected from different parts of India. The number of alleles per microsatellite locus ranged from 2 to 4, averaging 2.79 alleles per locus. Polymorphism information content (PIC) values ranged from 0...

with increasing the world population, and needing to feed it, the yield enhancement of cereals crops is of the most important approaches meet this target, which is achieved via identifying the effective factors underlay yield of cereals like wheat. this experiment was conducted to evaluate the grain yield and its association with some contributed traits in a doubled-haploid (dh) wheat populatio...

Wheat is one of the most widely distributed crops worldwide and is of primary importance as food for human nutrition. Increasing the productivity of the new wheat varieties according to the specific climate of the region is a permanent major task. The impact of environment and some agronomy practices (previous crop and mineral fertilization) on the productivity and the structural elements of yi...

a partial set of diallel crosses conducted among seven bread wheat genotypes contain (gasspard,m86-4,m86-6,dn-11,ws82-9 and m86-12) along with 21 hybrid, based on randomized complete block design(rcbd) with three replication were evaluated. the experiment was accomplished in a research field of agriculture and natural research center of tehran province in 2012-2013 in order to study genetic ana...

quantitative valuations of observed heterosis for 11 traits of 15 f1 hybrids generated by half diallel crosses of six diverse rice cultivars (domsefid, hashemi and binam, three iranian local cultivars; dorfak, kadous and ir30, three improved cultivars), were made in this study. fifteen f1 hybrids and their parents were evaluated in a randomized complete block design with three replications at t...
