Abstract
Soybean Breeding for Shading Tolerance and Intercropping. Asadi, DM. Arsyad, H.
Zahara, and Darmijati. Soybean growth under intercrop is usually supressed due to competetion with the taller crops for light, nutrients and water. Therefore under intercrop with the taller crops such as corn, cassava, soybean yield is usually lower compared to monoculture crops. At 33% shading intensity or intercropping with com, yield reduction of soybean could be 30-50%. High yield variability of soybean genotype under shading and intercropping, give high opportunity to conduct breeding program for developing improved varieties with tolerance to shading and intercropping. Research Institute for Food Crop Biotechnology (formerly Bogor Research Institute for Food Crops) has developed soybean varieties that tolerance to shading and suitable to intercrop with corn. Based on evaluation of soybean germplasm, B8306-4-4 genotype was indentified as a gene resource for shading tolerance and intercropping with corn. Yield evaluation of B8306-4-4 genotype along with some other genotypes at different locations and seasons under monoculture and intercropping with corn, indicated that B83O6-4-4 genotype was most promising. This genotype was released as recomended variety, named Pangrango.
