Yield change of seed bulb according to annual field culture after induced meristem culture in garlic (Allium sativum L.)

In this research, we surveyed the yield change of garlic cultivation with seed bulbs according to annual field culture after induced meristem culture. From 2007 to 2013, yearly produced seed bulbs from 2 nd to 8 th generation were cultivated in the Muan field. Over the generations, the general growth characteristics such as the plant height, leaf number, leaf length and stem diameter were all decreased. When we compared the conventional seed bulbs and TCR ones, the plant height and stem diameter showed bigger difference. And the TCR seed bulbs showed a week late harvest time against the conventional ones. The yield of 2 nd generation was 72.3 g and 57.1 g for the 8 th generation. However every generation showed higher yield than conventional seed garlic's ones as 43.9 g. The yield index showed the same trend as 2 nd - 8 th to 63% to 21%. After the tissue culture of garlics, the viral infections (OYDV and GSV) of TCR was far less than that of conventional ones. In case of LYSV, the infection ratio was 6.7% at 2 nd generation and 26% at 8 th . However, the ratio was far less than that (80%) of the conventional ones.
