Abstract
Nine interchange trisomics were isolated in the progeny of interchange heterozygotes in M3 generation; frequency of trisomics was found to be genotype specific. Morphologically they might be called as pale greenish, elongated stipule, reduced internode, weak-slender with elongated stipule, slender with round stipule, reduced stipule and leaflets, dark green, elongated internode and small-thick-errect leaflets. At MI, characteristic configurations were 104+5II+1I (46.2% cells) and 1III+6II (31.1% cells). At Al, 7-8 disjunction was most frequent ranging from 34.6 to 78.7%. Seed yield was very poor; only 1 to 4 seeds per plant were harvested.
