Abstract
Somaclonal variation for morphological traits was studied in both control and mutagen (chemicaland physical) treated progenies of two varieties of Solanum viarum. The SC1, SC1M1 (first generation followingtissue culture) and SC2, SC2M2 (second generation) of both 2n and 4n varieties on field evaluation showedbidirectional variation for plant height, plant spread, number of flowers and fruits per node and fresh fruitweight. Variation was more in number of fruits per node and fresh weight in physical mutagen treated progeniesin both the generations. The qualitative variations observed were less spine plants, dwarf plants, sterile planttypes and complete pollen sterility. The frequency of variations was different between varieties to varyingdegrees. SC2 and SC2M2 progenies on evaluation revealed increased variability compared to seed control for allthe traits indicating that these variabilities are not epigenetic in natur
