Abstract:

Abstract: Northeast China is a major ecoregion for soybean production in China, while Keshan area is a major soybean production area in northern of Northeast China. The soybean germplasm population composed of 361 landraces and released cultivars collected in Northeast China was tested in Keshan in 2012-2014 for evaluation of its characterization and genetic potential in local breeding programs. The results obtained were as follows: 1) the average performances with ranges of agronomic and seed quality traits were characterized as that the days to maturity was 133 d(103.8-157.0 d), the protein content /oil content /total protein and oil /100-seed weight were 39.69%(35.6%-44.38%), 20.58%(17.47%-22.84%), 60.27%(54.00%-63.97%)and 17.61 g(6.13-28.17 g) , the plant height, nodes on main stem, number of branches and lodging score were 96 cm(54.92-146.8 cm), 19 nodes (11.23-25.83), 2.75(0.22-7.63) and 2.18(1.00-4.00), respectively- 2) The MG 0 and MG I were the best adapted maturity groups that could fully use the local frost-free period with the averages of all traits similar to the population averages. The other maturity groups performance differently in Keshan. The MG 000 and MG 00 matured at about 110-120 d, 10-20 d earlier than the local first frost; the seed quality traits were better than those of MG 0/MG I with oil content /protein–oil content about 1%/1.5% higher; while their plant height and nodes on main stem were about 10.40 cm and 2.8 nodes less than those of MG 0/MG I. The MG II toke about 150 d and could not mature constant-naturally before the first frost; their seed quality traits were not as good as MG 0/MG I with protein content /protein–oil content about 2% less and oil content 0.5% less than those of MG 0/MG I, the plant height and nodes on main stem were about 10 cm and 2 nodes more than those of MG 0/MG I; while the lodging score were one grade more (grade 3) than that of MG 0/MG I. The MG III did not mature naturally, causing abnormal development of the other traits with growth amount and lodging score increased- 3)There are certain breeding potential for all the agronomic and seed quality traits according to the estimates of genetic gains, even oil and protein contents, which was demonstrated by a number of superior cultivars been released based on the germplasm population. From the present data, a group of superior accessions were nominated as parental materials for the improvement of individual traits of the adapted-local cultivars in Keshan area.
