C. S. Hsu, I. K. Wang
Tainan (S) No. 3, a newly developed mungbean variety introduced from AVRDC, has been included regional and local yield trial for two years (1980~1981) in Tainan and other districts.
Yield of Tainan (S) No. 3 is greater than local variety and Tainan (S) No.1. The average yield per hectare reached 2070 kg in local test. It is registered and released in 1981.
The original line of Tainan (S) No.3 is VC, 1628-A derived from a cross between CESID-21 (V. 3476) and PHL, V-18. The desirable characters of Tainan (S) No.3 is following:
1. Tainan (S) No.3 has erect plant type, the plant height is 54~68 cm, therefore it is not easy to lodge.
2. Most pods of plant are reached on upper portion of the plants and the maturity of pods is uniform, therefore more than 80% of pods will be harvested at once. It saves the labor of harvesting.
3. It has larger grain than that of Tainan (S) No.1. The weight of 1000 grains is 53~62 g.
4. It is more tolerate to powder mildew disease and lodging than Tainan (S) No.1.
For the release of Tainan (S) No.3, we hope that it will be acceptable for the farmers in Chia-nan area where is the major production area of mungbean in Taiwan. We also try to plant the mungbean in summer (July-August) in paddy field.
