Abstract

The experiment analyzed the genetic variation in morphological traits in x - ray irradiated groundnut (Arachis hypogaea L.) to assess adaptation to humid environment. Seeds of four soybean varieties; MS – 54 – 76, ICGV – SM – 42, RMP – 12 and SAMNUT 21, were exposed to six levels of x - ray irradiation; 0, 40, 60, 80, 100 and 120 KV at the rate of 28 mili Ampere per seconds. The experiment was laid out in split plot design, in three replicates. There were increases in the 100 seed weight, number of pods per plant, weight of pods per plant, weight of seeds per plant and shelling percentage in M2 than in the M1 implying that x – ray created beneficial variation in the cultivars. The x – rays also reduced the number of days to maturity and number of days to flowering in M2. Phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) in all traits.....
