Physio-biochemical characterization in wal

Abstract

The field experiment was carried out to study the physio-biochemical basis of yield variation in twenty different wal (Lablab purpureus L.) genotypes at education and research farm, Dept. of Agril. Botany, College of Agriculture, Dapoli during rabi 2016-17. The experiment laid out in randomized block design with three replications. T7, T8, T13, T14 and T19 were showed superior performance for all the physio-biochemical traits. Rate of photosynthesis varied from 12.97 to 23.47µmol CO2 m-2 s-1. Stomatal conductance observed between 0.174 to 0.337 µmol m-2 s-1. Transpiration rate ranged from 6.08 to 9.11µmol H2O m-2 s-1. The range of chlorophyll content recorded during 60 days period is 0.854 mg/g to 1.300 mg/g. Physio-biochemical characters can be effectively used for identification and grouping of varieties which can be further used for breeding programme.
