Abstract This study estimated the genotype × environment interactions for ten yield associated traits in advanced generation hybrids of several cultivars common wheat ( Triticum aestivum L.) with Aegilops kotschyi Boiss. and A. variabilis Eig. using additive main effects multiplicative interaction (AMMI) models. Tests were ran over five years at one location replicated field trials. The AMMI mo...

Among cereal crops, wheat has been identified as a major source for human food consumption. Wheat breeders require access to new genetic diversity resources satisfy the demands of growing population more with high quality that can be produced in variable environmental conditions. The close relatives domesticated wheats represent an ideal gene pool use breeders. genera Aegilops and Triticum are ...

Background Breeding of cereals has been particularly active in the last hundred years, resulting in spectacular improvements in agronomic, resistance or technological traits. Unfortunately for predisposed consumers wheat may induce allergenicity either food or respiratory. More recently, the genetic modification (GM) technology for crop improvement has emerged and although GM wheats are not cul...

This paper examines common factors that constrain wheat yields: insufficient nutrients (using nitrogen as an example); problems of late planting and poor crop establishment; suboptimal water management; lodging; and weeds. The authors suggest agronomic practices, including tillage practices, rotations, and input management options that can ameliorate important constraints and sustainably improv...

The inclusion of untreated rye or barley in poultry diets as a major ingredient causes growth depression. This is due to the high level of pentosans in rye (Antoniou and Marqurdt 1981) and the b-glucan content in barley (Gohl et al. 1977). It has been reported that some wheat cultivars grown in the eastern part of Australia show an unexpectedly low apparent metabolisable energy (AME) (~13 MJ/kg...

Components of resistance conferred by the Lr46 gene, reported as causing "slow rusting" resistance to leaf rust in wheat, were studied and compared with the effects of Lr34 and genes for quantitative resistance in cv. Akabozu. Lr34 is a gene that confers non-hypersensitive type of resistance. The effect of Lr46 resembles that of Lr34 and other wheats reported with partial resistance. At macrosc...
