In the 1992-1997 period, we tested the following in fodder galega (galega orientalis Lam.) variety 'YU Margarita RB-Mag -1/97': the 1000 grains mass in grams, seed viability, germinability, hard grains and total germinability in percentages. The testing was conducted in the following fine agricultural-ecological areas in FR Yugoslavia (R Serbia) : Bačka, Banat, eastern Serbia, Sumadija, western Serbia. According to the testing conducted, it can be stated that the weight of the 1000 grains mass ranged from 5-4 (1992) to 9.2 (1997) grams, the average for 1992/97 being 6.5 grams Seed viability ranged from 33,4% (1994) to 51,2% (1992), the average for 1992/97 being 41,13% and depended on the percentage of hard grains and agricultural-ecological conditions in the years of testing. Seed viability decreases with the increase in the percentage of hard grains. The hard grain content was 42,5% at the average in 1992/97. and ranged from 39.2-46.4%. The grain hardness is the property of this variety and species, and variation by year of testing depended on agricultural-ecological conditions of battening. The ratio between seed viability and hard grains is 1:1, namely, the reduction of hard grain contents increases the percentage of seed viability and vice versa. Total germinability (hard + germinated grains) ranged from 75.8 (1996) to 90.4 (1992), the average for 1992/97 being 81,8%. The variability of this property was considerably affected by agricultural-ecological conditions in the year of production and the agricultural-ecological areas in which the testing was conducted. The testing should be continued in order to establish whether the hard grain content diminishes with the years of age of seed and how long this new fodder crop of the legume family and species can preserve its seed viability and germinabilily for the following sowing. In our testing conducted so far, high seed viability and germinability were preserved even after 6 years, the percentage of hard grain decreased, and germinability increased (Table 1).
