Abstract
he main objective of this study was to evaluate the genetical potentialities of some sunflower lines through :
1-Using the cytoplasmic male sterility programme, 2- Using the artificial male sterility technique, and 3- Planting these lines in saline soils as a stress condition . That evaluation give an idea about which the genetical behavior of these lines differ in three cases or not .
Three experiments were conducted at El-Serw Agric. Res. Station, Egypt.(RCBD ) of three replications was used. The first experiment :-
In 1998 summer season, the five restorer lines were
crossed with the six CMS lines. In 1999 summer season, the thirty hybrids , the five testers and the six fertile lines (B lines) were planted .
The second experiment :-
In 1998 summer season, the six ( B-lines ) were sown
,the plants used as female were male sterilized a solution of gibberellic acid ( 0.5 mg GA I 3 ml H2o ), A possible cross combinations without reciprocals were made between the six inbred lines giving a total of fifteen crosses . In 1999 summer season, the fifteen hybrids , and the six fertile lines (8-lines) were planted.
The third experiment:-
In 1998 summer season, all the genotypes used in the first experiment were planted in soils (EC = 4.1 m mhos/em and ph = 8.3 ).
From the present study the results show that :-
The parental line 9 was the best in the first Exp. chiefly
in yield and yield component but its behavior changed in the second Exp. which has not significant in yield and yield component except oil percent and changed in third
