Mass Selection for Improvement of Pod Length and Yield of Snake Bean (Vigna unguiculata subsp. sesquipedalis (L.) Verdc.) in the Fifth Generation

Snake bean (Vigna unguiculata ssp sesquipedalis L.) is including one of important vegetables in this world especially in tropical and subtropical region. The production of snake bean in Malaysia cannot achieve the market demand. So, to fulfill the market demanding in Malaysia it is needed to increase the yield of the bean. This research was discussed about the method used to increase the yield of the snake bean. Therefore, the objective of this research was to improve the yield of snake bean by improving the pod length through mass selection. Two hundred and forty seeds of snake bean selected from fourth generation were grown in nine plots. The pods length greater than 75 cm were selected and dried and the seed from those pod will be used for the next generation. From this research, the mean of pod length of population increased compared to previous generation (fourth generation) from 54.31cm to 56.49 cm.
