GENETIC BEHAVIOUS OF SEGREGATING POPULATIONS OF ‘DESI’ X ‘GULABI’ CROSES OF CICER ARIETINUM L.

Abstracts

The  F₂ and F₃ populations each of two  ‘desi’  X  ‘gulabi’ crosses, viz.JG-1260  X JG-4 and JG4 X PRR-1 along their ‘gulabi’ (JG-4) and ‘desi’ (JG-1260  and PRR-1) parents were studied at the Research station of J.N Krishi Vishwa Vidyalaya,  Jabalpur ,during  1981-82. Highly significant differences were seen for days of flowering,  maturity and plant height in both crosses, for pods per plant, seeds per plant and 100-seed weight in JG-4 X PRR-1 and for number of secondary  branches only in JG-1260  X  JG-4.  The genotype variance  was found to be predominant for days to flowering and maturity JG-4 X PRR-1.  The major portion of genotypic  variance was found additive in nature for days to flowering in both crosses,  for plant height (JG-1260  X  JG-4),  number of seeds,  pods per plant and 100-seed weight in JG-4 X PRR-1.
