Yield potential of blast-infected seedlings of rice Oryza sativa in Peninsular Malaysia

Supaad Mohd Amin, . Yield potential of blast-infected seedlings of rice Oryza sativa in Peninsular Malaysia. pp. 98-100. ISSN 0126-5709

The effects of transplanting seedlings infected with leaf blast were evaluated on three rice varieties namely Setanjung Sri Malaysia II and Jaya. The levels of seedling infection were critical in determining the survival rate of transplanted seedlings in the main fields. At 50 level of infection about 39 43 and 81 of the seedlings survived and the corresponding plot yields at harvest were 70 71 and 88 of those of healthy seedlings for Sri Malaysia II Jaya and Setanjung respectively. If only a 5 reduction in yield can be tolerated the levels of infection should not be more than 20 for Setanjung and 12 for both Sri Malaysia II and Jaya

Abstract

The effects of transplanting seedlings infected with leaf blast were evaluated on three rice varieties namely Setanjung Sri Malaysia II and Jaya. The levels of seedling infection were critical in determining the survival rate of transplanted seedlings in the main fields. At 50 level of infection about 39 43 and 81 of the seedlings survived and the corresponding plot yields at harvest were 70 71 and 88 of those of healthy seedlings for Sri Malaysia II Jaya and Setanjung respectively. If only a 5 reduction in yield can be tolerated the levels of infection should not be more than 20 for Setanjung and 12 for both Sri Malaysia II and Jaya
