Resistensi Genotip Anggrek Phalaenopsis terhadap Penyakit Busuk Lunak

>

Soft rot disease caused by a bacteria Erwinia carotovora ssp. Carotovora is an important disease on phalaenopsis. To get resistant genotypes of phalaenopsis to soft rot diseases, an experiments was conducted at Segunung from April to December 2002. The resistancy of eight phalaenopsis genotypes to soft rot diseases was evaluated. The result showed that the P.6505 and P.503 genotypes were the most resistance to soft the rot diseases than the other genotypes. Resistant genotypes to this disease could dicrease of bactericide application. This genotype can also be used at a genetic resources to create new genotypes of phalaenopsis that resistant to soft rot diseases.
