An interspecific cross involving Cicer arietinum L. and C. judaicum (B
oiss) No. 182 was established. The F-1 could be distinguished from the
parents by its prostrate growth habit at the seedling stage and throu
gh isozyme patterns for peroxidases and esterases. The inheritance of
PRX-3 was found to be relatively simple and behaved as a monomer. Meio
tic studies indicated the occurrence of six bivalents and four univale
nts in about 6% of F-1 PMC's at metaphase I, but normal 8-8 chromosoma
l distribution in anaphase I, indicating near complete homology. The F
-1 hybrid was characterized for three morphological and six agronomica
l characters. A large F-2 was studied for secondary branches per plant
, 100-seed weight (g), pods per plant, and grain yield per plant (g).
Distributions of F-2 for pod number and grain yield displayed high C.V
. and were highly skewed in a positive direction. F-2 recombinants wer
e isolated with a very large number of secondary branches and a high p
od number and yield. Such wide variability is not normally encountered
in intevarietal crosses.
