Pendugaan Kriteria Seleksi Genotip Kedelai
Abstract: The implementation
of the selection that refers to the use of genetic parameter value might expect
very effective help in accelerating the discovery of a superior genotypes in
accordance with plant breeding program. Twelve promissing lines and check
varieties of soybean were planted at KP Sitiung Dharmasraya on two seasons
namely MT1 from August-November 2009 and MT2 from December to March 2010.
Fertilization with a dose of 75 kg of urea was 125 kg SP36 and 75kg of KCl/ha,
the plot size is 2.80 m x 4.0 m. A randomized complete block design with four
replication. Variable measured were agronomic characters, yield component and
yield. The results the experiment indicated that heritability of all the
characters were high (50,43% - 95,98%). Only heritability of plant high at MT1
and yield both environments was medium. The value of guess heritabilitas high
on productive branch character per plant and pods per plant is supported by
genetic advances and coefficient of average genetic variation is quite high and
high, thus both these characters can be reference selection criteria to get
productive branches per plant and pods per plant.
