Common bean is a worldwide important crop. The development of varieties with durable resistance to diseases major challenge in common breeding. present study aimed at evaluating the phenotypic and molecular selection anthracnose population obtained by assisted backcrossing from IAC Formoso (resistant, donor parent) × BRS Pérola (susceptible, recurrent parent). Nine microsatellites (SSRs) one Se...
Maize plants (Zea mays) attacked by caterpillars release a mixture of odorous compounds that attract parasitic wasps, natural enemies of the herbivores. We assessed the genetic variability of these induced volatile emissions among 31 maize inbred lines representing a broad range of genetic diversity used by breeders in Europe and North America. Odors were collected from young plants that had be...
Achieving optimal results in breeding programs require to make informed choices of parents based on general and specific combining ability. Determining of the combining ability and genetic variance components is one of the most important stage in breeding program of maize inbred lines. For this purpose, the number of 25 early maturity lines with two testers (k1263/1 early and late A679) crossed...
Purpose: Embryonic stem (ES) cells are derived from the inner cell mass of blastocysts with self-renewal and pluripotency characteristics. These cells have potential for studies of in vitro differentiation, gene function, etc. This study was, therefore, initiated to establish new ES lines and evaluate the effects of strain on ES cell production. Materials and Methods: 3-5 day blastocysts were ...
Popcorn consumption in Brazil has grown significantly over the years, and genetic improvement is essential to obtain sustainable gains multiple traits supply this increasing demand. Thus, objective of review was contribute information concerning process popcorn breeding tropical regions, germplasm availability, plans, main characteristics related quality yield, advances perspectives improvement...
To identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. The measured characters consisted of peduncle weight, ...
this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
Maize occupies a significant place in the world agriculture. Yellow kernel maize contains mainly non-provitamin A carotenoids: lutein and zeaxanthin. The accumulation of provitamin carotenoids is regulated by favourable alleles lcyE crtRB1 genes could be used for enhancement these grain through breeding. In this study, molecular screening Romanian germplasm was performed, looking genes, level d...
Bread’s quality depends on wheat flours quality and quantity and for the goal to be achieved, the usage of suitable wheat varieties should be considered. Present study focuses on analyzing doubled-haploid lines of wheat’s bread backing quality and the relationship between qualitative traits and glutenins reservoir proteins. In current work, traits related to bread backing quality of 30 doubled-...
Low temperatures are important for the production of spring maize in northern China. While low-temperature tolerance seeds can be improved by coating them, this result environmental pollution, high costs, and instability. Therefore, identifying new varieties is most effective method improving ability crops to withstand low temperatures. In experiment, four tolerant inbred lines (DNF266, Zhong 4...
