DAYA TUMBUH KECAMBAH DAN WAKTU BERTUNAS KACANG HIJAU (Vigna radiata L.) GENERASI F3

Abstract

The improvement program of mung bean (Vigna radiata .L) can be done by crossbreeding, selection, and testing of the progeny to obtain new varieties. This study aims to analyze the growth ability and germination time of mung bean sprout, F3 generation. The study was conducted at the experimental station of Biology, Faculty of Math and Natural Science, University of Riau from January to April 2015. A total of 693 mung beans seeds (F2 generation) were planted and observed. The results showed that the skin color of mung beans pods (F3 generation) have a variation. The grouts ability of mung bean sprout growth ability (72,22%) was F2-13 while the lowest (11,90%) is shown by F2-15. In Kenari and Kampar parent, the percentage of sprout growth ability were 61,9% and 57,14%, respectively. The bud forming time of mung bean (F3 generation) ranged from 5,60 to 6,83 days. The fastest forming time was found in F2-14 plot with 5,6 days in average. While the slowest time of forming bud was found in F2-12 plot with an average of 6,8 days. The germination time of Kenari and Kampar sprout were 6,17 and 6,12, respectively.
