Abstract
Twenty four prickly lettuce genotypes were studies for phenotypic and
genotypic variability. broad sense heritability (his). phenotypic coefficient of variation
(PCV). genotypic coefficient of variation (GCV%), genetic advance (GA%) of yield and
yield components, selection index (SI), phenotypic and genotypic correlation and
path coefficient. Significant variations were observed between genotypes for most
studied traits during the two seasons (20032004 and 2004f2005).The highest
genotypic and phonotypic variations were observed for oil yield, seed yield and
number of branchesfplant, respectively. All the traits showed high heritability values
with high genetic advance except for number of branchesfplant in both seasons.
Selection index (St) was estimated for all genotypes of prickly lettuce.
Genotypes number : 20, 8, 1 and 2 are considered to be promising for oil yield and
oil content. Path coefficient analysis revealed the importance of seed yield per plant
and oil content of all genotypes in both seasons. In general. results of genetic
parameters (P.C.V, G.C.V. habits, GA%, and SI and path coefficient analysis) showed
the importance of all or most studied traits especially seed yieldfplant, oil content %
and oil yieldiplant as selection criteria in prickly cl: lettuce crop.
