The Analysis Of The Strain Influence On Some Yield Elemnts On An Assortment Of Isogenic Wheat Varieties

In the years 2012-2014 on Banu-Maracine DRS were tested an assortment consists of 25 isogenic lines of common wheat (Triticum aestivum ssp.vulgare), with the combination of Rht1&rht8 genes, the analyzed characters being the hight of the strain (cm), the number of seeds/spike, seeds weight/spike (g), no. of spikes/m², weight of a thousand seeds (WTS) (g) and no. of emerged plants/m². Based on recorded data and statistical processing of those, they were identified a numbers of links between these characters, links quantified by using the correlation.

Regarding the classification based on the average high of the strain, it was found that that there is a strong link between some characters too. Based on component analysis, the no. of seeds/spike and the seeds weight/spikes are components that influence in excess of 83% variance analysis, a total of five genotypes having positive scores for both factors.
