dc.description.abstractA field experiment was conducted during kharif, 2014 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, to study the growth, physiology and productivity in black seeded soybean (Glycine max (L.) Merrill.) mutants and parents. The mutants and their parents and local checks used were KHSb2 Parent, KHSb2 Tall mutant, KHSb2 Dwarf mutant, Kalitur and DSb-21. The experiment was laid out in randomized block design (RBD) with four replications. Significant differences were observed in morphological, growth, physiological, biochemical, yield, yield components and quality parameters among genoytpes. The biophysical parameters such as rate of photosynthesis, stomatal conductance and rate of respiration were higher with DSb-21, Kalitur and KHSb2 dwarf mutant. Further, data on SPAD values and the seed phenol content revealed that KHSb2 parent had maximum chlorophyll content and KHSb2 dwarf mutant had higher phenol content among all the genotypes under investigation. All the yield and yield components viz., number of pods per plant, number of seeds per pod, seed weight per plant, seed yield (q ha-1 ) were significantly higher with DSb-21 and was closely followed by KHSb2 dwarf mutant. Data on quality parameters like seed oil and seed protein contents revealed that seed oil percentage was higher in KHSb2 dwarf mutant and seed protein content was higher with Kalitur. The correlation studies clearly indicated that LAI and LAD at almost all the stages had very high positive association with seed yield, thus signifying the role of assimilatory surface area in yield determination. From the present investigation it is inferred that two promising entries viz., DSb21 and KHSb2 dwarf could be used as source of improving dry matter partition and test weight as they proved superior over their parents and check varieties for these traits.en_US
