Soybean growth under intercrop is usually suppressed due to competition 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 percent shading intensity or intercropping with corn, yield reduction of soybean could be 30-50 percent. 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 Crops Biotechnology (formerly Bogor Research Institute for Food Crops) has developed soybean germplasm, B8306-4-4 genotype was identified 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 B8306-4-4 genotype was most promising. This genotype was released as recommended variety, named Pangrango
