Field experiments to identify the flowering ability, flowering duration, percentage of flower abortion, and yield potential of several soybean varieties were conducted at two environments at Kendalpayak- Malang Research Station in April-July 2006 (dry season I) and Genteng-Banyuwangi Research Station (dry season II) in July- October 2006. A total of 20 soybean varieties were evaluated by using randomized complete-blocks design with three replications. The plot size was 0.8 m x 4.5 m with plant spacing 40 cm x 15 cm. The rate of fertilizers applied was 50 kg urea, 100 kg SP36, and 75 kg KCl per ha. Plant control was conducted intensively as recommended. Several characters observed were time to flower, flowering duration, number of flower, number of pod, number of filled pod, number of empty pod, seed yield/plant, and 100 seed weight. Combined analysis of variance show that all characters oberved were significantly affected by varieties. Flower abortion of soybean varieties range from a low of 6.6% for Lawit to a high of 39.1% for Kawi. Lawit variety was used as high yielding potential parent which has lowest percentage of flower abortion (6.6%) and highest percentage of flower to pod (93.4%).
