Effect of mutagens on character association and selection response in mutagenised populations of Grasspea (Lathyrus sativus l.)
Character association and component analysis at genotypic level were studied in mutagenised populations (M2) of grasspea land race “Dhenkanal local” following seed treatment with gamma-rays, EMS, NG and their combinations. Seeds/plant emerged as an independent direct yield contributing trait in all treatments except 40kR gamma-rays + 0.2% EMS. In general, number of branches/plant, pods/plant and seeds/plant exhibited very high and significant positive association with seed yield/plant.
