Four lines of Triticum durum, representing diverse levels of genetic relationship and geographic origin, were crossed to produce six segregating populations. Additive and dominance components of genetic variance were estimated for five metric characters in the F2 and F4 generations grown in separate years. Dominance variance predominated in two out of the six populations in F2, but was minimal in the F4 generation. Additive genetic variance generally constituted the major source of genetic variance and was significantly greater than zero in all populations for every character investigated in F4. Populations based on crosses involving either of the two Ethiopian selections with either of the two North American varieties used as parents, in general showed larger amounts of genetic variance than the comparable intercross of the two North American varieties. Considerable genetic variance also existed in the populations derived from intercrossing the two Ethiopian wheats. The results of the investigation tend to support the hypothesized increase in genetic variance associated with genetic diversity, and the preponderance of additive genetic variance in naturally self-fertilizing species.

Blood fever and Chikungunya cases in Indonesia are increasing annually. For preventing the mosquios, people use mosquito coil which is contain dangerous chemical compound. This research has successly created a natural mosquito coil with gemor bark and hazelnut fruit shell as the main material. Gemor bark is positive containing alcaloid,tanin, phenolk, flvonoid, triterpnoid and glycocydic compounds which are natural bioinsecticide. As formulation the comparison of gemor bark and hazelnut shell as follow :100% : 0 %  ; 80 % : 20 % ; 65 % : 35 % ; 50 % : 50 % ; 35 % : 65% and 20 % : 80% were used. Base one random variance analysis, the best formula was the using of gemor bark in 50%, 35% and  20% of concentration. The mosquitos killing force analysis was using the LT50 for 6 days with 5 diferent concentrations. The result showed that 50 %  of gemor bark was significantly influenced in the killing force. From the economic view, the producion of this coil was cheaper then the same product in the maket. Base on all the result, the research product is applicable in mass producion and safe for human health and the environment.Keywords: gemor bark , hazelnut fruit shell ,  mosquito coil, natural ,  ecofriendly
