-Wheat is the most important crop of many countries including Pakistan. Assessment of Yield stability of wheat in different environments has been an important issue for wheat growers and horticulturists. In present paper yield stability of wheat genotypes is assessed at different research institutions/stations across the country using univariate parametric stability models and interrelationship...

Developing high yielding and stable genotypes for wide and specific adaptation is important in wheat (Triticum aestivum L.) production. The objective of this study was to exploit the gains from genotype by environment interaction for increased bread wheat production in eastern Africa. Thirty-three advanced bread wheat lines, along with two check varieties (Danda’a and Hidasse) were evaluated at...

RAPD-PCR genetic markers were used to assess variation in wheat plants and connections among six genotypes. Four random primers produced 140 DNA fragments, averaging 6.7 identifiable bands per primer. Among the genotypes, 85 pieces (44.64 percent) polymorphic. Several RAPD marker had distinct signify recurrence patterns that thing differently amongst germplasm of groupings. Within-community acc...

Random amplified polymorphic DNA (RAPD) analysis was employed to estimate genetic diversity/genetic similarity among nine wheat (Triticum aestivum L.) genotypes. Out of 25 random 10-mer primers surveyed, 18 primers detected polymorphism among all the wheat genotypes, while 7 primers produced monomorphic pattern. A total of 175 bands were amplified, 60.57% of which were polymorphic. Genetic simi...

In order to study planting date impacts and ending season drought stress  on grain yield and  gaining weight  rate  and wheat filling period characteristics in new advanced bread wheat genotypes ,this research  is done by using plan statistical  of spilt plot  in form of complete random blocks basic  plot with 3 replications in both common separated irrigation  and ending season drought  stress...

The objective of this experiment was to study of water relations and chlorophyll in different wheat genotypes and their correlations with grain and biological yields. 21 genotypes of bread wheat were compared in a field experiment as randomized complete blocks design with four replications. The results showed that relative water deficit, relative water loss, excised leaf water retention, cell m...

Water stress during meiosis in wheat is a major constraint to yield especially for the rainfed farming regions. Pollen sterility has been proposed as the most sensitive process leading to low seed set (low % of fertile spikelets), but here we show this is not universal, and that the development of female reproductive parts is equally if not more sensitive than male parts in many wheat cultivars...

Experiment was designed to establish a more defi nitive relationship of phenological and physiological traits with yield in wheat using twenty fi ve spring wheat genotypes. Because many of these traits are interrelated, correlation coeffi cient, path analysis and principal component analysis were used to expose these relationships more clearly. Experiment was conducted at the Wheat Research Cen...

Genetic diversity is essential to meet the diversified goals of plant breeding such as producing cultivars with increased yield, wider adaptation, desirable quality, pest and disease resistance. In this study genetic diversity and selection index of 24 genotypes of bread wheat were evaluated. The performance of 24 wheat genotypes showed that there were significant variations for the characters ...
