In Brassicaceae crop breeding programs, wild relatives have been evaluated as genetic resources to develop new cultivars with biotic and abiotic stress resistance. This has become necessary because of the diversification of ecotypes of diseases and pests, changing food preferences, advances in production technology, the use of new approaches such as in vitro breeding programs, and the need for ...
Salinity is an important limiting factor in the production of more plants, including rice. Due to the limited amount of cultivated area, identification of tolerant genotypes to environmental stresses and especially salinity is very important. The aim of this study was to investigate the genetic diversity among 114 recombinant lines derived from the intersection of local Tarom × Khazar cultivars...
The International Center for Maize and Wheat Improvement (CIMMYT) leads the Global Wheat Program, whose main objective is to increase the productivity of wheat cropping systems to reduce poverty in developing countries. The priorities of the program are high grain yield, disease resistance, tolerance to abiotic stresses (drought and heat), and desirable quality. The Wheat Chemistry and Quality ...
In maize, doubled haploid (DH) technology is used in breeding programs to obtain lines, the primary input for developing new cultivars. This review aims present main points related using this steps its application, and advantages implications of DH lines maize programs.
Genomic prediction is expected to considerably increase genetic gains by increasing selection intensity and accelerating the breeding cycle. In this study, marker effects estimated in 255 diverse maize (Zea mays L.) hybrids were used to predict grain yield, anthesis date, and anthesis-silking interval within the diversity panel and testcross progenies of 30 F(2)-derived lines from each of five ...
Introduction of apomixis, asexual reproduction through seeds, into crop species has the potential to dramatically transform plant breeding. A new study demonstrates that traits can be stably transferred between generations in newly produced apomictic lines, and heralds a breeding revolution needed to increase food production for the growing planet.
the current study was conducted to investigate the effect of short-term divergent selection on the shape growth curve in different lines of japanese quail. the quail lines utilized in this study were two divergently selected for high (hw) and low (lw) 4-wk body weight during 7 generation and also a control line (c). the richard function parameters were used to describe growth curves of differen...
In order to identify the most important traits affecting yield in maize inbred lines and hybrids, an experiment was conducted in Shushtar City in 2009 and 2010 years. Fifteen inbred lines in 2009 and 28 hybrids in 2010 studied in two planting dates, 6 July (to coincide heat stress with pollination time and grain filling) and 27 July (normal condition) using a randomized complete block design wi...
'Dwarf stature' maize variety offers promises to withstand unfavorable growth environments of Kharif season. But, for developing such variety, dwarf stature inbred lines must be available. Here, twenty-four F3 populations of white maize were evaluated though assessment of their genetic variability, heritability, and character association for selection of dwarf stature promising lines based on y...
