Persilangan Genotipe-Genotipe Kedelai (Glycine max L. Merrill.) Hasil Seleksi pada Tanah Salin dengan Tetua Betina Varietas Anjasmoro

Abstract

The aim of the research was to cross the resistant generations of the saline soil from pedigree selection of grobogan varieties with female parent of Grobogan varieties as one of the stage to obtain the varieties which resistant to the saline condition. The research was carried out in plastic house Agriculture’s Faculty of North Sumatera University, Medan, Indonesia with ± 25 m altitude above sea level. which was held in April to July 2014. This research used Completely Randomized Design with five combination crossing and ten replicant that is Grobogan×N , Grobogan×N 3 , Grobogan×N 4 , Grobogan×N . Parameters observed were the percentage of the succeeded crossing, number of productive pods, number of empty pods, number of pods contain one seed, number of pods contain two seeds, number of pods contain three seeds, and weight of 10 seeds per plant. The results showed that crossing between selected of soybean genotypes on saline soil with Grobogan varieties as female parent significantly different for parameters number of productive pods, number of empty pods, number of pods contain one seed, number of pods contain two seeds, number of pods contain three seeds, and weight of 10 seeds per plant, but not significantly different for parameters the percentage of the succeeded crossing. Key words : crossing, genotype soybean, saline soil. 5 1 , Grobogan×N 2
