Atanassova, B. Inheritance studies on
Studies were carried out in
some components connected with
diallel cross 8 x 8 involving
exerted stigma in tomatoes and
the following tomato lines,
the influence of different
cultivars and species:
environments on its manifestation.
GCR-66, Rutgers 21, Red
cherry, Penelopa, Line 7/3,
Line XXIV-13, L. hirsutum f. glabratum, L. pimpinellifolium No. 108 (Table 1).
Four flower parts controlling the manifestation of exserted stigma were
measured: filament, anther, style and ovary. For studying the influence of
different environments, the measurements were made according to clusters
(from 1st to 5th), and trials were carried out under field and glasshouse
conditions in 1974 and 1975.
It was shown that except the hybrids involving the wild species L.
pimpinellifolium No. 108 and L. hirsutum, the filament and the ovary practically
did not play any part in the manifestation of exserted stigma, showing
intermediate inheritance. Therefore, first consideration was given to anthers
and style. The inheritance of these two components in F1 was studied by means of
the genetic parameters for dominance and additivity (Falconer 1960).
