Abstract

Soybean is an important food crop in Indonesia. One of the major problems in soybean production was a virus infection, with CpMMV as one of the most important viruses. The process of plant breeding to produce virus resistant soybeans and high productivity can be done by crossing virus resistant line with superior varieties. Important information in plant breeding program development of resistant varieties and high-productivity was to know the genetic of the trait, one of which is the maternal effect. The purpose of this study was to analyze the inheritance of maternal effects through the agronomical characters of F1 soybeans derived from the crossing of the Panderman variety and the CpMMV-resistant soybean lines. The experiment used a randomized block design with three replications. The results showed that the maternal effect was found out on the seed yield per plant for Panderman x UM61. Five crosses showed the maternal effect on the weight of 100 seeds namely Panderman x UM24, Panderman x UM34, Panderman x UM61, Panderman x UM63, and Panderman x UM73. Maternal effect on plant height was only found out in Panderman x UM62 cross. The maternal effect was also found on the number of unfilled pods in Panderman x UM34 and Panderman x UM61 crosses.
