VARIABILITAS GENETIK DAN HERITABILITAS KARAKTER AGRONOMIS BEBERAPA GENOTIPE SORGUM MANIS (Sorghum bicolor L. Moench) KOLEKSI BATAN
Abstract: This research aims
to determine the genetic variability and the heritability character of
agronomic some sweet sorghum genotype (Sorghum bicolor (L.) Moench) collection
of BATAN. This research has been conducted in Field Experiment and the plant
breeding laboratory, Faculty of Agriculture, University of Riau from April 2013
to September 2013. This inquiry has been carried on experiments using a
randomized block design (RBD) consist of 13 treatments and 3 replications that
contained 39 experimental units. Treatment consists of 13 genotypes, there are
Patir-1, Patir-2, Patir-3, Patir-4, Patir-5, Patir-6, Patir-7, Patir-8,
Patir-9, Patir-10, Kawali, Mandau and Pahat. The outcome showed that Patir-9
was the genotype with the best result because it bears a weight of seeds per
panicle, 1000 grain weight and output per m2 higher than other genotypes. Plant
height and panicle length wide genetic variability, whereas the other
theatrical roles suffer a narrow variability. Characterization of plant height,
number of leaves, number of segments per plant, dry weight, panicle length,
grain weight per panicle and yield per m2 has a high heritability value, a
character who receives a moderate heritability value that stem diameter and weight of 1000 seeds,
while the fiber takes in low heritability values were age flowering.
