					pods/plant and number of seeds/pod should be effective to increase
yield potential in lentil.

   Zaman et al. (1989) found positive correlation between seed
yield/plant and each of number of primary and secondary
branches/plant and time to 50% flowering. These characters were also
significantly correlated among themselves except for the association
between number of seeds/pod and time to 50% flowering. They
concluded that profusely branched plants with a high number of pods
tended to have a higher yield potential.

   Luthra and Sharma (1990) studied correlation and path analysis
in 56 lentil genotypes for ten characters. They reported that, number
of pods/plant; biological yield/plant and number of seeds/plant were
highly and positively correlated with seed yield. Significant and
negative association was observed between number of seeds/pod and
100-seed weight. Path analysis revealed that biological yield/plant is
the main contributor towards seed yield.

   Waldia et al. (1990) studied correlation between germination and
some shoot and root characters of lentil seedling. They found positive
and significant correlation between percentage of seed germination
and 100-seed weight.

   Hamdi et al. (1991 a) study association between economic
characters in lentil over a wide range of genetic material and
environments in West Asia. They conducted two experiments, the first
experiment concerned correlation within large samples from the world
lentil collection (3663 accessions) grown in two seasons, and the
second experiment covered a smaller sample of genetic material (34
genotypes) from the collection sown over a wider range of conditions
(10 environments).
   In the first experiment, seed yield was strongly positively
correlated with straw yield and harvest index and negatively correlated
with times to flowering and maturity and protein content. Harvest
index showed positive association with seed yields and number of



                                  40
seeds/pod, and negative association with plant height and lowest pod
height. Seed protein content was strongly and positively correlated
with times to flowering and maturity, and negatively correlated with
seed yield and harvest index.
    In the second experiment seed yield was correlated positively with
straw yield, number of pods/plant, 100-seed weight, harvest index,
and cooking time but was negatively correlated with number of
seed/pod. Time to flower showed positive associations with plant
height and seed protein content. The relationships among yield
components, showed weak association between number of pods/plant
and each of 100-seed weight and number of seeds/pod. Moreover,
there was a strong negative correlation between 100-seed weight and
number of seed/pod. These results indicate that it would be difficult to
achieve a response to selection for high level of these two characters
simultaneously.

   Jain et al. (1991) studied multiple correlation and regression in six
varieties of lentil. The results indicated that a combination of two or
three variables, viz. height/plant, branches/plant and pods/plant, was
found better than other combinations of the characters for the
imbrovement of seed yield.

   Khattab (1992) studied the relationships among various lentil
characters in Egypt. His results showed that, seed yield/plant was
positively and significantly associated with pods/plant, seeds/pod,
100- seed weight, biological yield and harvest index, but negatively
and significantly correlated with time to maturity. Path analysis
revealed that 100-seed weight, pods/plant and seed/pod had the
highest contributions to yield variation either through its direct effects
and/or its indirect effects with traits while, branching, plant height and
time to maturity had minor contributions. He concluded that 100-seed
weight; pods/plant and seeds/pod could be considered as main
selection criteria in lentil improvement.

   Kumar-Sanjai and Bajpai (1993) reported strong positive and
significant correlation between seed yield and each of plant height,



                                   41
primary and secondary branches, number of pods/plant and biological
yield. While, negative correlation has been found between number of
seeds/pod and 100-seed weight, and between 100-seed weight and
number of secondary branches.

   Esmail et al. (1994 b) studied correlation and path coefficient
analysis at phenotypic and genotypic levels on F5 segregates of two
lentil crosses. Results indicated that seed yield/plant was negatively
correlated with time to maturity at phenotypic levels in ILL 5584 x
Precoz cross and at phenotypic level in Giza 370 x Precoz cross and at
phenotypic level in Giza 370 x Precoz cross. Suggesting the
possibility of selecting early-high yielding lines, at both levels, seed
yield was positively correlated in lines. At both levels, seed yield was
positively correlated in ILL 5584 x Precoz cross, but negatively
correlated in Giza 370 x Precoz cross with seed protein content. Seed
yield was also positively correlated with each of branching pods/plant,
seeds/pod, seed weight and biological yield/plant at both levels in the
two studied crosses. Path coefficient analysis indicated that branching,
pods/plant and seeds/pod were the most important characters affecting
yield variation in studied material and should be considered be
considered in lentil selection programs.

    Abo-Shetaia et al. (1997) reported that seed yield of lentil was
significantly correlated with pods/plant (0.795).

     Kusmenoglu and Muehlbauer (1998) studied genetic variation
for biomass and residue production in lentil in USA in 1993-95. The
objectives of this study were (1) determine the relationship between
physiological and morphological traits that affect biomass and residue
production and (2) identify suitable selection criteria for increasing
biomass and residue production by lentil crops. Some 39 breeding
lines were evaluated at 3 sites in Washington and Indiana each year
during 1933-95. Straw yield in 1993 was correlated with days to
flowering (r=0.72), days to maturity (r=0.82), plant height (r=0.76),
harvest index (r=-0.97) and seed yield (r=-0.71). In addition, there was
significant correlation between straw yield and harvest index (r=-0.48)
