Morphological variants in khesari.

The effect of gamma rays on ‘P 10’, ‘P 24’, ‘P 288’, ‘P 293’, ‘P 585’ and ‘LC 76’ and differential and combined effect of gamma rays and 0∙2% MES on ‘P 288’ of Lathyrus sativus L. in relation to morphological changes have been described. The segregation pattern of seed-coat colour mutants have been discussed. Although different varieties responded differently, no morphological variants were observed in ‘P 585’ at any dose.
