ISOLATION OF TWO TRANSLOCATION HOMOZYGOTES IN MUNGBEAN (VIGNA RADIATA (L.)WILCZEK)

Published on

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.
