Abstract


To support of the breeding program, create new varieties that have the characters of high production and good quality seed for product which should be conducted identification / characterization of soybean germplasm. This study aims to determine the diversity of soybean germplasm in morphology character and the degree of association between traits. A total of 110 soybean germplasm were acrried out at Cikeumeuh Experimental Station ICABIOGRAD Bogor from April to July 2013. The experimental design used randomized block design with 2 replications. Plot size is 1.2 x 3 m with 1 plant accesion per planting. The seed germplasm were planted with a spacing of 40 x 15 cm. The N-P-K fertilizer used equivalent of urea 50 kg/ha, SP 36 100 kg / ha, and KCl 100 kg/ha. The results showed that the 110 soybeans accessions were characterised with slight height diversity as weight of 100 seeds and yield/plot. The character observed a range out as 33-106 cm plant height, 2-5 number of branches, 28-57 days flowering phase, 73-104 days to maturity, 19-113 number of pods, 83% fulfill pod, 5-21 gram weight of 100 seeds and 65-717 g yield/plot. Significant correlation were obtained between the number of pods and number of branches on yield of soybean. Height yield soybean were supported number of pods and number of branches that were selected of more accessions such as 6/3/21/7/1 (Introduksi USA), Detam 2 (Jawa Timur), PW-4 (Jawa Tengah), Lokal Pasuruan (Jawa Timur), Lokal Karangasem (Bali), and Kedele Godek 2 (Jawa Barat).
