Genetic variation for grain mineral content in tropical-adapted maize inbred lines.
Increasing the concentrations of Fe and Zn in staple food crops through breeding has been proposed as one strategy to minimize the adverse effects of widespread mineral deficiencies in humans. This approach requires the presence of adequate genetic differences in concentrations of grain minerals for improvement. Eight trials involving different sets of tropical maize inbred lines adapted to the...
متن کاملGenetic Analysis of Grain Yield and Yield Components in Bread Wheat using Hayman's Diallel Method
Extended Abstract Introduction and Objective: By progeny trial after a diallel crossing, the function of genes and inheritance of quantitative traits can be estimated. This increases the ability to select parental lines, to participate in crosses, and determines the management of generations in the segregating populations. Material and Methods: In order to understand the genetic structure of ...
متن کاملGenetic analysis of seed yield and oil content in safflower using F1 and F2 progenies of diallel crosses
Improvement of seed yield and oil content in safflower (Carthamus tinctorius L.) as an oilseed crop is the main objective of its breeding programs. However, little genetic information is available for these traits. The main objective of this study was to estimate genetic parameters for seed yield and oil content. Six safflower lines each derived from different Iranian local populations and Saff...
متن کاملDetermination of levels of Striga germination Stimulants for maize gene bank accessions and elite inbred lines
Parasitism by Striga hermonthica (Del) Benth is a severe constraint in maizeproduction in sub-Saharan Africa. Varying levels of tolerance to Striga attack havebeen identified and exploited in breeding programs of several crops. However, thelevel and stability of the tolerance is generally unacceptable in field-practice. Onlylimited exploration has been undertaken among the farmers’ landraces to...
متن کاملDiallel Analysis of Grain Yield and Some Important Agronomic Traits in Bread Wheat
Extended Abstract Introduction and Objective: Wheat is one of the most important crops in the world that plays a key role in ensuring food security. In wheat breeding programs, selection of genotypes with desirable agronomic traits and high yield potential have always been the goal of plant breeders. Increasing the selection efficiency for grain yield depends on genetic knowledge from morpholo...
