Keragaan dan Keragaman Galur - Galur F5 Kedelai Hasil Metode Single Seed Descent dari Persilangan Argomulyo x Tanggamus

Abstract

The objectives of this experiment to get information on agronomic performance and variation of F5 soybean lines developed by single seed descent method from Argomulyo x Tanggamus. This experiment was conducted at Augmented Design in Randomized Complete Block Design (RCBD) genotype as the single factor. The genotypes tested were 125 F5 lines with no replication and 3 checks consisted of variety Tanggamus, Argomulyo and Wilis replicated six times. This experiment was conducted at Leuwikopo experimental field and the Plant Breeding Laboratory, Department of Agronomy and Horticulture, Bogor Agricultural University from April to September 2014. Results of this experiment showed high variation among F5 lines in plant height, number of nodes per plant, number of productive nodes per plant, number of full pods per plant, and number of pods per plant. Those characters were not significant with Tanggamus and higher than Argomulyo. The highest heritability and broad sense genetic variation was found for plant height, number of nodes per plant, number of productive nodes per plant, number of full pods per plant, number of pods per plant, and weight seed per plant
