Abstract

Soybean {Glycine max (L.) Merr.} varieties with consistently high yield productivity across environments are expected to maintain its production level per area.The objectives of this experiment are to determine the magnitude of G × E interaction and to identify the stability of eight soybean promising lines across locations. Materials consists of eight soybean promising lines (G100H/SHRW-60-38, SHRW-60/G100H-73, SHRW-60/G100H-68, SHRW-60/G100H-66, G100H/SHRW-34, SHRW-60/G100H-5, SHRW-60/G100H-70 and SHRW-60/G 100 H-75) and two check varieties (Kaba and Wilis). The experiments were done in 16 locations (Lampung Tengah, Yogyakarta, Ngawi, Mojokerto, Pasuruan, Malang, Banyuwangi and Lombok Barat, two locations each) during the period of 2009 to 2011. A randomized completely block design with four replicates was used in each location. AMMI analysis (Additive Main Effects and Multiplicative Interaction) was applied to assess the yield stability of those 10 genotypes, and then interpreted in biplot graphic of seed yield for principal components 1 (IPCA1) with the principal component 2 (IPCA2). Seed yield of the 10 soybean lines ranged from 2.63-3.02 t/ha, with 2.81 t/ha in average. The highest yield was obtained by G6 (SHRW-60/G100H-5), whereas G3 (SHRW-60/G100H-68) had the lowest seed yield.The combined analysis showed that lines, locations, and the interaction of lines and locations (G × L) were significantly different for seed yield.The first four Interaction Principal Component Axes (IPCA1, IPCA2, IPCA3 and IPCA4) were significant and accounted for 85.1% of the total GEI. Lines of G100H/SHRW-60-38 (G1), SHRW-60/G100H-66 (G4) and SHRW-60/G100H-5 (G6) were stable and high yielding, and therefore they are proposed to be released as new varieties. The results of this study also suggested that Kaba and Willis were used as specific-check varieties, due to its site-specific adaptability.

Abstract

Recent demand of black soybean {Glycine max (L.) Merr.} seed has been rising for industrial raw material. A total of five promising lines of black soybean (9837/K-D-8-185, 9837/K-D-3-185-195, W/9837-D-6-220, 9837/K-D-3-185-82 and 9837/W-D-5-211) were evaluated for the potential yield at 18 soybean production centrals in West Java, East Java, Bali and West Nusa Tenggara, from 2004 until 2006..Variety of Cikuray (black soybean), Wilis (famous variety with high yield) and Burangrang (large seed size and short maturation day) were used as check varieties.The field experimental design for each location was completely randomized design with four replicates.The treatment consist of eight lines/variety with 2,4 m × 4,5 m plot size, 40 cm × 15 cm plant distance, two plants/hill.Fertilizer of 50 kg Urea, 100 kg SP36 and 75 kg KCl per ha were applied before sowing time. Weed, insect and disease were controlled intensively.Stability analysis was according to Eberhart and Russell (1966), and adaptability was by Finlay dan Wilkinson (1963). Location, genotype and interaction between 2genotype x environment (G × L) were significant for seed yield. Estimate of environment variance component (d L = 0.0604) was the 2 2 biggest one, and followed by error variance value (d E = 0.0470), genotype variance (d G = 0.0258) and the smallest was estimate of 2 interaction variance G × L (d GL = 0.0225).Significant interaction of G × L showed that each promising lines have specific reaction to certain location quality. Five promising lines were able to produce 2.44 until 2.51 t/ha, or 17% higher than black soybean variety of Cikuray (2.03 t/ha); or 10% higher than Burangrang and 3% more higher than Wilis. Genotype of 9837/K-D-3-185-195, W/9837-D-6-220, 9837/K-D-3-185-82 and 9837/W-D-5-211 were indentified stable. Genotype of 9837/K-D-3-185-195, W/9837-D-6-220, 9837/K-D-3-185-82 and 9837/W-D-5-211 were promising to be high yielded and adaptable across location; on the contrary, genotype of 9837/K-D-8-185 was more adaptable in optimal location.
