The simplified AFLP method was developed and evaluated for identification and genetic diversity studies of wheat cultivars. Selective primers exploited in AFLP assay based on a single cutting enzyme PstI ((PstI)AFLP) generated total of 111 robust fragments, including 67 (60%) monomorphic and 12 (11%) cultivar-specific markers. Average similarity between 15 cultivars was 0.650, and varied from 0...

An isoelectric focusing method capable of resolving all groups of storage protein of the wheat seed, including the most basic low molecular weight glutenin (LMWG), was developed. Ultrathin polyacrylamide gels were used after drying and rehydration with 8 M urea, 50 mM DTE and 2.4% carrier ampholytes (pH 4-9). Densitometric scanning of the isoelectric focusing gels permitted a more accurate and ...

To meet the growing demands under the constrains of depleting natural resources, environmental fluctuation and increased risk of epidemic outbreak, the task of increasing wheat production has become daunting. The euphoria generated by first green revolution is very quickly subsiding and the second generation problems are becoming more intense with each passing year. The factors responsible for ...

Of the various chlorophyll abnormalities that occur in polyploid wheats, genetic bases of only two types, chlorina and virescence, are known. Here, for the first time, the chromosomal bases of three other chlorophyll abnormalities, striato-virescence, delayed virescence, and albino, which occur in Emmer wheat (2n = 4x = 28, genome constitution AABB) are reported. A set of disomic substitution l...
