Diallel analysis of the duration of vegetation period in tomato (Solanum lycopersicum L.) with increased lycopene content in the fruit
<p> Five parental forms of tomato (Solanum lycopersicum L.) and twenty hybrids F1, were studied which were obtained by the complete diallel scheme (5 x 5). For genetic analysis (by Hayman, 1954; Jinks,1954) was used line №477 (sp,u), variety Alya (sp) with reduced duration of vegetation perio...

| Sumario: | <p> Five parental forms of tomato (Solanum lycopersicum L.) and twenty hybrids F1, were studied which were obtained by the complete diallel scheme (5 x 5). For genetic analysis (by Hayman, 1954; Jinks,1954) was used line №477 (sp,u), variety Alya (sp) with reduced duration of vegetation period and three collection samples with the high lycopene content in fruits: Dark Green (hp-2dg), МО 112 (hp), Т˗3627 (Bc). The effects of the general (GCA) and specific combining ability (SCA) of the duration of vegetation period were determined and established character of inheritance. According to the results of research, the duration of vegetation period is controlled by additive-dominant genetic system. Inheritance occurs by type of over dominance, and in dry and hot summers which led to the prolongation of the duration of vegetation period, there is a tendency to incomplete dominance, but it is apocryphal. In genetic control a major role play non-additive effects of genes. The best reliable effects of the general combining ability (GCA) had line №477 and variety Alya. They can be recommended for the creation of heterotic hybrids and varieties.</p> |
