Abstract

A total of 27 papaya fruit samples were collected in December, 1987. Twenty were from Chiang Mai and 7 from Chiang Rai province. All the samples were planted in August, 1988 in the field plot of the Center Laboratory and Greenhouse Complex. Only 13 collections from Chiang Mai and all 7 from Chiang Rai bore fruits. These fruits were harvested and evaluated. The result showed that most of the plants were tall and late flowering type, giving low yield. The fruit of all collections had yellow and thick flesh of soft texture but thin skin. One collection from Chiang Rai was found to be homozygous recessive as all their progenies had yellow leaves, flowers and fruits which were susceptible to disease.

Abstract

Meristem culture of five cultivars of sugarcane, namely, Supan, Nigro, Macos, E-Heudang and CO were cultured on Marashige and Skoog media with 3 mg/l or 1 mg/l 2, 4-D including 10% (v/v) coconut water. The plantlets obtained were detected for the presence of sugarcane mosaic virus by using the enzyme-linked immunosorbent assay (ELISA), with alkaline phosphatase and p-nitrophenyl reaction system. Results were evaluated by automatic reading machine and percentage of virus-free stock were determined. It showed that sugarcane plantlets derived from meristem culture provided upto 80-100% virus-free plants which could be mass propagated for further plantation in the field.
