Abstract

The aim of this study was to obtain information on plant growth rates involving leaves, stem, pods, and seeds, to be used as selection criteria in breeding program, to develop early-maturing soybean cultivar with higher yield than Grobogan variety. The experiment was carried out at ILETRI’s experiment station in Ngawi, East Java during dry season I. Seeds of five soybean genotypes including Grobogan variety were planted on 24 June 2010. Growth rates of leaves, stem, pods and seed were analyzed using linear and quadratic equations. Results showed that Grobogan variety yielded the highest of 2.9 t/ha. There were no genotypes having earlier leaves growth rate (source strength) higher than that of Grobogan variety. The G2 genotype (Sinabung/Argomulyo 415-2) had higher assimilate partition rate to the seed (sink strength) compared to that of Grobogan variety, namely 0.386 g/plant/day and 0,288 g/plant/day, respectively. To improve yield potential through sink strength, a cross of G2 (Sinabung/Argomulyo) and Grobogan is suggested.
