Low temperature during reproductive stage of spring wheat causes sterility of pollen grains and reduced yield. Field experiment was conducted during the winter season in the farm of Indian Agricultural Research Institute with wheat crop to study the effect of temperature on phenology and pollen sterility of spring wheat crop. Lower mean temperature during the crop growth period led to enhanced ...

Food security is a global concern and substantial yield increases in cereal crops are required to feed the growing world population. Wheat is one of the three most important crops for human and livestock feed. However, the complexity of the genome coupled with a decline in genetic diversity within modern elite cultivars has hindered the application of marker-assisted selection (MAS) in breeding...

Genetic differences among major types of wheat are well characterized; however, little is known about how these distinctions affect the small molecule profile of the wheat seed. Ethanol/water (65% v/v) extracts of seed from 45 wheat lines representing 3 genetically distinct classes, tetraploid durum (Triticum turgidum subspecies durum) (DW) and hexaploid hard and soft bread wheat (T. aestivum s...

development of new cultivars with high grain yield (gy) stability and good adaptability under both terminal drought stress (tds) and normal irrigation conditions, which plays important role in production of wheat, is one of the major goals of wheat breeding program for cold dry areas of iran. the objective of this investigation was to study the stability and adaptability of gy and genotype × lo...

Singh, R. P., Bechere, E., and Abdalla, 0. 1992. Genetic analysis of resistance to stem rust in ten durum wheats. Phytopathology 82:919-922. Durum wheat (Triticum turgidum L.) cultivars derived from CIMMYT present in Mexicali 75, Diver, Somorguho, and Morus together with (International Maize and Wheat Improvement Center) germplasm are an unidentified gene, SrC, and in Altar 84, Carcomun, Totanu...

To introduce new genetic diversity into the bread wheat gene pool from its progenitor, Aegilops tauschii (Coss.) Schmalh, 33 primary synthetic hexaploid wheat genotypes (SYN) were crossed to 20 spring bread wheat (BW) cultivars at the International Wheat and Maize Improvement Center. Modified single seed descent was used to develop 97 populations with 50 individuals per population using first b...

yekta was created in 1981 from crossing between b5 ? m7 and an early maturing palistinian line, in oil seed crops research department of seed and plant improvement institute (spii) at karaj. the pure line of the cross was obtained after five years of selection with pedigree method. preliminary evaluation of the line along with other 31 selected lines was done in 1989 and yekta together with oth...

The predicted world population increase along with climate changes threatens sustainable agricultural supply in the coming decades. It is therefore vital to understand crops diversity associated to abiotic stress response. Heat stress is considered one of the major constrains on crops productivity thus it is essential to develop new approaches for a precocious and rigorous evaluation of varieta...

MicroRNAs (miRNAs) are small non-coding RNAs that play critical roles in plant development and abiotic stress responses. The miRNA transcriptome (miRNAome) under water deficit stress has been investigated in many plant species, but is poorly characterised in durum wheat (Triticum turgidum L. ssp. durum). Water stress during early reproductive stages can result in significant yield loss in durum...
