The relationship among some Quantitative Characters of Different Varieties of Soyabean (Glycine Max (L) Merrill.) in the Sudan Savannah Agro-Ecological Zone of Nigeria

This research experiment was conducted at Teaching and Research Farm of Kano University of Science and Technology, Wudil (Latitude 11°51’ N, Longitude 9°20’ E at an altitude of 430 m above the sea level). The aim of the study is to study the relationship among some qualitative characters of different varieties of Soybean in the Sudan Savannah region. The germplasm of three different varieties of Soybean improves, namely TGX-1448-2E, TGX-1835-10E and one local variety were collected from Bayero University Kano Agronomy Laboratory and local market around the region. The seeds were sown in a randomized complete block design and replicated nine times. Days to 50% flowering, plant height, number of leaves /plant, number of pods/plants, number of seed per plant, seed yield/plant, and 100-seed weight were taken as growth and yield parameters. The result of analysis of variance indicated that all the growth and yield parameters were significantly (P>0.05) different between the varieties except plant height at 4WAS which was found to be statistically similar among the three varieties. Plant height at six weeks after sowing had positive and significant correlations with the number of pods per plant (0.254), days to 50% flowering (0.214) and negative significant correlation with the number of seeds per plant(- 0.30). Days to 50% flowering showed negative but highly significant correlations with the number of pods per plant (-0.870) and the number of seeds per plant (-0.659) however, it only shows positive and highly significant correlation with hundred seed weight (0.524). The number of pods per plant had positive and highly significant correlations with the number of seeds per plant (0.759) and negative significant correlation with hundred seed weight (-0.564). The number of seeds per plant showed negative and highly significant correlations with the hundred seed weight (-0.441)
