GENERAL AND SPECIFIC COMBINING ABILITY OF INITIAL PARENTAL FORMS IN TOMATO FOR COMPLEX OF ECONOMICALLY VALUABLE TRAITS TO DEVELOP HYBRIDS F1 OF CHERRY AND COCKTAIL TYPES
Results of estimation of general and specific combining ability of male and female parental tomato forms were given for complex of traits. The estimation was carried out according to incomplete diallel crosses 15x15. Such varities as ‘Trapeza’, Rosovaya kapelka’, ‘Seniorita’, ‘Ocharovanie’, ...

| Summary: | Results of estimation of general and specific combining ability of male and female parental tomato forms were given for complex of traits. The estimation was carried out according to incomplete diallel crosses 15x15. Such varities as ‘Trapeza’, Rosovaya kapelka’, ‘Seniorita’, ‘Ocharovanie’, ‘Tigris’ ‘Vishnya Zheltaya’ (Gavrish), ‘Denezhnoye Derevo’ (national breeding), and lines: ‘46/06’, ‘49/09’, ‘295/09’, ‘336/11’, ‘354/11’, ‘357/11’, ‘388/09’ (nor), ‘498’ (selection of TARI) were used as intial breeding accessions, differing in bush type (determinate and indeterminate), duration of vegetative phase (ultraearly, early, medium early, middle-ripening), fruit shape (rounded, oval), fruit color (red, pink, black, orange, tiger and with the gene nor), fruit weight (10 g. and more), brush structure (dense, friable). As a results, ‘Trapeza’, ‘Vishnya Zheltaya’, ‘Ocharovaniye’, ‘Seniorita’, and lines: ‘295/10’, ‘49/09’, ‘498’, ‘357/11’, ‘354/11’, ‘388/09’ (nor) were selected and recommended to be used in breeding program for development of heterotic hybrids with high fruit setting and generative bush type. The promising hybrids F1 with high constants of specific combining ability for a complex of economically valuable traits have been observed. Because of different lines and accessions were used in crossings, these hybrids varied in internode length of cluster type, classical or shorten; rounded or oval fruit shape; fruit color, red (F1 combinations ‘354/11’ х ‘Seniorita’, ‘Trapeza’ х ‘L.49/09’, L. ‘49/09’ х L.354/11), pink (F1 combination ‘Rosovaya Kapelka’ х ‘L.354/11’), yellow (F1 combination ‘Ocharovaniye’ х ‘Vishiya Zheltaya’), deep brown (F1 combination ‘L.357/11’ х ‘L.354/11’). |
