Kalia N.R. | Gupta V.P.
In a study at the Himachal Pradesh Krishi Vishwa Vidyalay, India microsperma and macrosperma types of lentil seeds were irradiated with 5, 10, 15, 20 and 25 kR of gamma rays to study the nature and magnitude of induced variation in various polygenic traits in both lentil types. Data were recorded for seed yield, biological yield, harvest index, number of pods/plant, 100-seed weight, plant height, time to 50% flowering (days), and time to maturity (days). A sufficient genetic variability was induced for most polygenic traits in both lentil types. However, macrosperma type was found more radio-sensitive.
