MORPHOLOGICAL, CYTOLOGICAL AND PEROXIDASE ISOZYME STUDIES IN DIPLOIDS, HYBRIDS AND AMPHIDIPLOIDS OF VIGNA RADIATA AND V. MUNGO

Published on

Amphidiploids were developed from Ft hybrids of Vigna radiata and V. mungo, which
showed betlerperformance for most ofmorphological traits compared with Ftsbutnot their
parents. Better seed set in amphidiploids seems to have resulted from increase in bivalent
formation and increased normal disjunction. The codominant expression of
species-specific isoperoxidases was observed in interspecific hybrids and amphidiploids.
The isoperoxidases can, therefore, be used as markers for the identification of hybrids and
amphidiploids.
  

Keywords: Vigna radiata, Vigna mungo, interspecific hybrids, amphidiploids, isoperoxidases.
