									The relationship between number of branches and number of pods was
positive and highly significant, but negative and significant for
number of branches and seed weight. Number of pods was positively
and significantly correlated with seed weight.

   Tyagi and Sharma (1985) estimated correlation among some
economic traits in 19 promising Indian lentil varieties. They found
that 1000-seed weight had a highly significant and negative assocation
with seeds/pod. A significant negative association between time to
flower and 100-seed weight (r = -0.68) indicates that the most of the
Indian lentils are early flowering. Longer periods of flowering and
maturity produced more dry matter. Seed yield was positively
correlated with total dry matter. Harvest index was negatively
correlated with earliness, but positively correlated with seed yield.

    Balyan and Singh-Shobir (1986) investigated the association
among eight lentil characters and their direct and indirect contribution
to seed yield. The results showed that seed yield/plant was positively
and significantly correlated with plant height, number of
pods/peduncle, and number of pods/plant and biological yield at
phenotypic levels, suggesting the importance of these traits in
selection for yield. The path coefficient analysis revealed that number
of pods/plant and 100-seed weight exhibited high positive direct
contribution to seed yield. However, time to maturity and plant height
showed high positive direct contributions to seed yield at genotypic
level. The direct contribution of biological yield was positive at
phenotypic level, while it was negative at genotypic level. Thus, on
the basis of characters association and direct and indirect contribution
of characters to seed yield, it is concluded that plant height, number of
pods/plant, 100-seed weight, time to maturity and number of
pods/peduncle are the most important characters affecting
improvement in lentils.

    Mia et al. (1986) reported that positive correlation between seed
yield/plant and plant height, indicating that the taller plants may have
more bud bearing nodes and hence, higher seed yield. But seed yield

had negative association with 100-seed weight, time to flowering and
time to maturity. On the other hand 100-seed weight showed negative
correlation with time to flowering, plant height and seed yield. It may
be suggested that selection based on taller plant type with smaller seed
size is effective for high seed yield.

   Eissa et al. (1987) studied the performance of nine lentil
quantitative traits in two seasons in Egypt. They used 33 local
accessions (sub sp. macrosperma) of Lens culinaris, 13 foreign (sub
sp. microsperma) entries and the local commercial cultivars Giza 9
and Family 300. They found that days to first and mid flowering were
negatively correlated with seed yield/plant, pods/plant and harvest
index in the foreign entries. Seed yield was highly and positively
correlated with pods/plant in both subspecies. This correlation was
largely consistent a cross years. Path analysis revealed that pods/plant
exerted the greatest direct effect on yield in both subspecies.

   Baidya et al. (1988) calculated the phenotypic and genotypic
correlation coefficients for 6 quantitative traits in 96 lentil strains.
They indicated that the advantages of upgrading lentil genotypes
would be that expected through simultaneous selection for plant
height, dry weight/plant and number of pods/plant and branches/plant
have been recognized as major contributors to seed yield.

   Manara and Manara (1988) carried out a series of experiments
for three consecutive years in Brazil to study the relationship among
several lentil traits. They concluded that an increase in seed yield
could be obtained by selecting late maturing plants with a high
number of pods.

    Murari et al. (1988) concluded that in lentil number of branch,
number of pods and seeds/plant, plant height (in 1983 only) and 1000-
seed weights were positively correlated with seed yield/plant in both
1983 and 1984. While, seed yield and plant height was negatively
correlated in 1984. The contribution of different yield components to

seed yield/plant accounted for 93 and 96% of the yield in 1983 and
1984, respectively.

    Rao and Yadav (1988) found positive correlation between seed
yield and each of harvest index and biological yield. Concerning
heritability estimates, parameters of genetic variability and association
analysis, they concluded that selection criteria based on harvest index
and seed yield would serve the purpose of improvement of seed yield
in lentil.

    Ramgiry et al. (1989) reported that seed yield had strong positive
correlation with seed yield/plant, number of branches/plant, number of
pods/plant and harvest index. Harvest index showed strong positive
correlation with seed yield/plant, number of branches/plant and
number of pods/plant, but no association was noticed between harvest
index and 100-seed weight. Number of branches/plant and number of
pods/plant had also positive correlation with seed yield/plant. Number
of pods/plant was negatively correlated with 100-seed weight. In
conclusion, harvest index, seed yield/plant, number of branches/plant
and number of pods/plant have been recognized as major contributors
to seed yield.

   Rajput and Sarwar (1989) calculated correlation among various
lentil characters in 22 diverse lentil genotypes. They revealed that
seed yield was positively and significantly correlated with number of
pods/plant and number of seeds/pod. Number of pods/plant appeared
to be the most important component of yield. The other yield
contributing traits, plant height, number of branches/plant and pod
length showed positive, but non-significant effects on seed yield. 100-
seed weight had negative association with plant height and number of
pods/plant. Plant height had strong positive correlation with number of
pods/plant. They concluded that selection on the basis of plant height
is useful in improving seed yield. On the basis of variability
parameters and association analysis of different characters with seed
yield, it was suggested that selection criteria based on number of
