| dc.description.abstract | Soybean is a food crop that is widely cultivated in Indonesia. Soybean needs are increasing both used
for food and non-food industry raw materials. Making varieties by crossing several superior varieties is
expected to produce soybean varieties that have better properties than their parents. Before the
crossing of plants, it is necessary to know in advance the characteristics of the plants to be crossed.
This study aims to determine the agronomic character of 5 soybean varieties along with 20 results of
dialel crossing and to determine the growth response and yield of 5 soybean varieties with 20 yields of
dialel crossing. The crossed varieties include Dega-1, Gemasugen-1, Gemasugen-2, Sinabung, Gema.
Based on the results of the study showed that twenty results of crosses and five generations of F
1
soybean parents showed significantly different results on parameters of plant height, number of fertile
books, number of primary branches, age of flowers, harvest age, number of pods, number of empty
pods, number of seeds per plants, seed weight per plant and weight of 100 seeds. Genotypes from
Gemasugen-2 and Dega-1 crosses have higher yield potential compared to other crossing results. The
results of the Gemasugen-2 crossing with Dega-1 and Gemasugen-2 with Gemasugen-1 also have
more early age (74 days) compared to other cross-bred soybean genotypes in the F1
generation. | en_US |
