Normal distribution of agronomic characters and plant heritability of soybean F2 population hybridization between salt resistance genotype and Anjasmoro variety

Abstract

The increase of soybean production should be pursued continuously, including the utilization of marginal land such as saline soils. This study aimed to estimate the frequency of normal distribution and heritability of agronomic characters of soybean F2 population hybridization salt resistance genotype and Anjasmoro variety to support the expansion of planting area in the saline land. The research was conducted at the Faculty of Agricultural land experiments using saline soil as planting media with salinity levels 5-6 dS/m was conducted in March to May 2015. The data were analysed using chi-square test for suitability distribution normal. The results showed the frequency of character plants height, the number of productive branches, flowering dates follow a normal distribution, while the frequency distribution of harvesting, number of seeds/plant and seed weight/plant does not follow a normal distribution. Heritability belonging to the high criteria on plant height, number of productive branches, harvesting, the flowering dates, number of seeds/plant and seed weight / plant belonging to the moderate criteria. The results showed the genetic potential of plants to be developed in saline land in support of the expansion of soybean planting in saline soil.
