Significant genotypic correlations among yield and its components were generally more prevalent than the phenotypic in the direct as well as reciprocal wheat crosses.

    Genetic diversity in barley from west China based on RAPD and ISSR analysis Yong-Cui Hou, Ze-Hong Yan, Yu-Ming Wei, You-Liang Zheng* as a source of important genes for cultivar development via interspecific crosses (Dávila et al. wheat (Nagaoka and Ogihara ), bean (Métais et al. ), Diplotaxis (Martín and Sánchez-Yélamo Abstract. Kernel morphology and texture influence the value of wheat (Triticum aestivum L.).The objectives of this study were to determine associations between kernel traits and molecular markers and to identify quantitative trait loci (QTLs) affecting kernel traits in a soft × hard white wheat cross.

    genetic and physiological mechanisms underlying natural variation for ST in wheat and to find ways to explore the inherent genetic variation, with the ultimate aim of finding new candidate genes that can be used to improve ST in wheat. The performance of genetically diverse wheat genotypes were evaluated under different salinityFile Size: 6MB. Wheat yield is largely determined by the grains per spike, which in turn is related to the fertile floret development prior to anthesis. The aim of this study was to assess the physiological mechanism of exogenous 6-benzylaminopurine (6-BA) on fertile floret development and grain setting characteristics by foliar application in winter wheat.

The high-molecular-weight (HMW) subunits of glutenin from about varieties were fractionated by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE).

About 20 different, major subunits were distinguished by this technique although each variety contained, with only a few exceptions, between 3 and 5 subunits.

Early Studies on Interspecific Hybridization. A newly formed allopolyploid wheat species results from an interspecific or intergeneric hybridization, followed by spontaneous somatic or, more likely, meiotic chromosome doubling in the sterile F1 or, alternatively, derived from crosses between parental species with unreduced gametes (Ramsey and Schemske ).Cited by: THE GENETIC APPROACH TO PHYSIOLOGICAL STUDIES IN BREAD WHEAT.

The huge amount of genetical and biochemical studies on wheat storage proteins, gliadins and glutenins, which started in the 80s, was the base for these achievements Cited by: 1.

There are a number of features that make lettuce suitable for genetic studies. It has a relatively short life cycle, it is fully self-fertile with a high rate of natural self-pollination, it is possible to carry out a large number of crosses on one plant, and individual plants require only a moderate amount of space.

Important characters in wheat Ploidy level. As with many grasses, polyploidy is common in wheat. There are two wild diploid (non-polyploid) wheats, T.

boeoticum and T. urartu.T. boeoticum is the wild ancestor of domesticated einkorn, T. monococcum. Cells of the diploid wheats each contain 2 complements of 7 chromosomes, one from the mother and one from the father (2n=2x=14, where 2n is the.

The IWGSC, with 2, members in 70 countries, is an international, collaborative consortium, established in by a group of wheat growers, plant scientists, and public and private breeders.

Foxtail millet has a typical domesticated plant architectural form consisting of a single stalk or a few tillers, with large inflorescences that mature more or less at the same time ().Its wild progenitor, green millet, has tillers and axillary branches that appear over the life of the plant, and inflorescences that readily shatter to release the seed at maturity (Defelice, ).

Breeding for pre-harvest sprouting (PHS) resistance in wheat (Triticum aestivum) and spelt (T. spelta) is difficult because PHS is quantitatively inherited and strongly affected by environmental factors.
