The seed bulbs of garlic usually come from local growers’ fields, these seed garlic have never selected for plant vigorous and screened for freeing from virus, therefore the garlic plant commonly appears a weakness of growth year by year in Taiwan. The promising plants were collected and indexed with complex garlic virus antiserum. The materials with negative reaction by ELISA, were propagated by bulblets to get mass multiplication. The results showed that 220 plant out of 670 stocked plants co. Early Indonesia, 48 plants out of 1792 collected Tapenhei plants, 4 plants out of 949 collected Pesun planted appeared a negative reaction. The stocked plants of cv. Early Indonesia had been indexed to free from the viruses with the same antibodies’ eradication of the plants showing and have propagated for years in a net house with mosaic at leaves the plants of cv. Early Indonesia appeared a high ratio of freeing from viruses in the indexing. The plants grown from these virus-indexed bulbs and bulblets previous generation, also appeared a high ratio of freeing from these viruses. It is conclude that the plants appeared a high ratio of freeing from these viruses. It is conclude that the plants free from viruses may be gotten from growers’ fields.
In general the propagation of garlic is by cloves, and the multiplication rate is 7.8 folds. At the experiment the cloves were stored at 5, 10 or 15℃ for various duration and the results showed that the bulbs stored at low temperature might induced production of bulblets. The treated plants with multiplication rate increased up to 18.3 folds were mature 26 days earlier.
