Evaluation of some inbred lines of yellow maize (Zea mays L.) using top-cross method under different environments

Forty-six inbred lines of yellow maize (zea mays L) crossed apically with Al Ghouta variety No. 82 during 2008 growing season at Dir Ala, Dead Sea.

Prediction of combining ability in some maize (Zea mays L.) inbred lines using top-cross method under different environments

This research was carried out to evaluate the combining ability of twentyfive inbred lines of yellow maize and estimate the phenotypic correlation and path analysis of twenty-five top crosses were formed during 2009 growing season at Dir Ala, Dead Sea. Jordan. Their plants were evaluated in Syria during 2009 growing season in three locations (Al Raka, Aleppo and Dir Al- Zor).

Variability, Correlation and Path Coefficient Analysis of Yield and Some Yield Components in Faba Bean (Vicia faba L.) Populations

In a study conducted at Research Center of Dara'a, General Commission for Scientific Agricultural Research during two growth seasons 2007/2008 and 2008/2009. 11 faba bean (Vicia faba L.) populations were planted in an experiment designed randomized complete blocks design with three replications. The objectives were investigation of phenotypic variance among populations studied, to determine the relationship among number of yielded branches plant -1, number of pods plant -1 , number of seeds pod -1, 10- green pod weight (g) and yield of green pods plant -1 (g) using correlation and path coefficient analysis. The combined analysis of variance showed highly significant differences among populations under study and for all characteristics studied, except number of yielded branches plant-1 where differences were only significant. The correlation and path analysis studies revealed that negative and highly significant relationship was found between number of yielded branches plant -1 and yield of green pods plant-1, while was positive and highly significant between yield of green pods plant-1 and 10-green pod weight. All direct effects of components studied were negative in both seasons, except 10-green pod weight, and these results suggested adopting the last component as a selection index during making selection of high yielding genotypes in faba bean populations. .

Path Coefficient Analysis and Relative Importance of Some Fodder Yield Components in Pearl millet [Pennisetum glaucum (L.) R. Br.]

This study was carried out at Kharabu Station, General Commission for Scientific Agricultural Research (GCSAR), during the growing seasons 2011 and 2012, to estimate phenotypic correlation, and path coefficient of some morphological and green fodder yield components (days to flowering, plant height (cm), number of leaves per plant, number of tillers per plant, and green fodder yield (ton/ha)). Fifteen pearl millet crosses resulted from half diallel mating system between six inbred lines. The experiment was arranged in a randomized complete block design (RCBD), with three replications.
