gourd (Coccinia grandis [L.] Voigt)' was conducted at the vegetable research
Farm of the Department or Olericulture, College or Horticulture, Vellanikkara
during the year 1996-1998. Twenty accessions of Ivy gourd were raised in
randomised block design. The accessions studied showed significant variations
among themselves for most of the characters studied. Accession CG-73
produced the longest fruit and the highest average fruit weight per plant whereas
accession CG-l1 produced maximum number of fruits per plant and maximum
yield. Accessions CG-23, CG-45 and CG-44 were found 10 be high of carotene,
vitamin C and calcium content respectively. Polyphenol was minimum in the
accessions CG-78 and CG-74.
High genotypic coefficient of variation combined with high heritability
was shown by characters like primary branches per plant, fruit yield per plant
and nodes to first flower production. Fruit per plant, average fruit weight, girth
of fruit and length of fruit showed significant positive correlation with yield.
Fruits per plant showed the highest positive direct effect on yield, Using
Tochers method the twenty accessions were grouped into four clusters each
having nine, five, five and one accessions having a distance of 3.325,
3.303,3.300 and 0.00 respectively. The solitary cluster IV consisted ofCG-73.
