Abstract Soybean aphid (Aphis glycines Matsumura (Hemiptera: Aphididae)) has been a major pest of soybean in North America since its detection in this continent in 2000 and subsequent spread. Although several aphid resistance genes have been identified, at least four soybean aphid biotypes have been discovered, with three of them being virulent on soybean cultivars with certain soybean aphid resistance genes. These biotypes are known to vary across years and locations, but information on their variation within single fields is limited. An investigation was conducted to study the variation of soybean aphid biotypes within single townships and fields in Minnesota. Screening of 28 soybean aphid isolates collected from seven soybean fields (six soybean fields in Cairo and Wellington Townships of Renville County, MN and one field in Wilmar Township of Kandiyohi County, MN) revealed the existence of multiple known biotypes of soybean aphid within single fields of soybean. We found up to three biotypes of soybean aphid in a single field. Two biotypes were found in five fields while only one field had only a single biotype. Three isolates presented reactions on a panel of resistant and susceptible indicator lines that were different from known biotypes. These results highlight the importance of characterizing soybean aphid biotypes in small geographical areas and utilizing generated knowledge to develop soybean cultivars pyramided with multiple resistance genes. The outcome will be decreased use of insecticides, thereby improving economic and environmental sustainability of soybean production.

<p>Identification of Early Maturing and High Yielding Soybean Germplasm. Preference to early maturing soybeans is higher than the late ones, since early maturing soybean can improve planting index and able to escape from fail of harvest due to drought stress. To identify accessions of soybean germplasm which will be used as gene resources in developing of early maturing and high yielding varieties, a numbers of 203 soybean germplasm accessions were evaluated at Jambegede Research Station on dry season 2006. Observation primarily conducted on physiological maturity and flowering date. Beside, observation also conducted on plant height, number of branches, 100 seeds weight and seed yield. Result showed that accession of MLGG 0751 and MLGG 0753 identified having early maturity (70 days). The early maturing accessions had lower yield than the late maturing ones. There was no accession having both of early maturing and high yielding traits. Accessions of MLGG 0751 and MLGG 0753 can be used as gene resources in developing of early maturing varieties.</p><p> </p><p><strong>Abstrak</strong></p><p>Preferensi terhadap kedelai berumur genjah lebih tinggi daripada berumur dalam karena kedelai berumur genjah dapat meningkatkan indeks pertanaman dan dapat menghindari kegagalan panen akibat cekaman kekeringan. Untuk mengidentifikasi aksesi plasma nutfah yang akan digunakan sebagai sumber gen dalam perakitan varietas kedelai berumur genjah dan berdaya hasil tinggi, sebanyak 203 aksesi plasma nutfah kedelai dievaluasi di Kebun Percobaan Jambegede pada musim kemarau 2006. Pengamatan terutama dilakukan terhadap umur masak fisiologis dan umur berbunga. Pengamatan juga dilakukan terhadap tinggi tanaman, jumlah cabang, bobot 100 biji, dan hasil biji tanaman. Hasil penelitian menunjukkan bahwa aksesi MLGG 0751 dan MLGG 0753 teridentifikasi berumur genjah (70 hari). Aksesi berumur genjah memiliki hasil biji lebih rendah daripada aksesi berumur dalam. Tidak diperoleh aksesi kedelai berumur genjah yang sekaligus berdaya hasil tinggi. Aksesi MLGG 0751 dan MLGG 0753 dapat digunakan sebagai sumber gen dalam perakitan varietas kedelai berumur genjah.</p>
