Pengujian terhadap Koleksi Genotipe Kedelai terhadap Penyakit Bisul Bakteri

Abstract

The objective of the research was to evaluate the resistance of soybean genotypes in the germplasm collection to pustule disease. Seventy five genotypes were evaluated using spray innocu- Iation method. Innoculation was done on the third week after planting. The 75 genotypes evaluated consists of 29 local varieties, 8 national varieties, 23 introduction, and 15 experimental lines. Results of the experiment showed that among the 75 genotypes tested, one local variety, Si Pinang was found resistant to the pustule disease (Xanthomonas campestris pv. glycines). The resistant local variety was collectedfiom Langkat, North Sumatra.
