Two translocation homozygotes were isolated in M2 generation of two semisterile lines
raised from seeds of mungbean variety NP 28 irradiated with interrupted 60 kR y-rays.
When crossed with marker standard type, one translocation homozygote produced
semisterile hybrid showinga chain quadrivalent +9 bivalentswhile the other translocation
homozygote gave rise to semisterile hybrid with a ring quadrivalent + 9 bivalents. The
translocation homozygotes, when intercrossed, produced highly sterile hybrid showing
two quadrivalents (one chain, one ring) +7 bivalents, indicating that the chromosome pairs
involved in interchange in the two lines were different.
Keywords: Mungbean, Vigna radiata, translocation homozygotes.
