Book Description
Ninety F1 hybrids obtained by diallel cross involving ten tomato genotypes displayed wide range of variation and heterosis for ten characters studied. Heritability was the highest for no. of fruit/cluster, fruits/plant, fruit yield/plant and no. of seeds/fruit. The highest genetic advance and genetic advance expressed as percentage were recorded for the characters no. of fruits/plant and no. of seeds/fruit. The genetic advance, coefficient of variability and heritability indicated that selection of superior parents based on these characters might be effective in hybridization programme to develop high performing tomato hybrids. Combining ability analysis showed that yield and yield component characters were found to be controlled by both additive and non-additive genes. Good combiner genotypes Japany, Epoch, Namdahri, Ratan and Legend possessed mostly dominant genes for all the characters. For QTL analysis F2 population was developed from a cross between two tomato genotypes Dynasagor and Bari-4. Five QTLs were identified with fruit yield/plant. Of five, three QTLs were contributed by the parent Dynasagor and two were contributed by parent Bari-4.

Book Description
This is a reference book which describes importance, use and basic information relevant to application of heterosis breeding in tomato for yield and quality contributing traits. Tomato is a tropical day neutral plant. It is self-pollinated crop but a certain extent of cross pollination may take place. It is a warm loving crop so easily tolerate heat and drought stress. India is the second top tomato growing country after China contributed about 11% of the World tomato production. Tomato is a rich source of antioxidants (mainly lycopene and -carotene), Vitamin A, Vitamin C and minerals like Ca, P and Fe in diet. Magnitude of heterosis, combining ability effects and its variances were estimated by line x tester analysis including 30 F1 cross combinations using 13 parents after selfing. These genotypes were evaluated for growth, yield and quality contributing traits. Ratio of general combining ability (GCA) and specific combining ability (SCA) variance revealed preponderance of non- additive genetic variances for all studied traits. Present book is basically written for Vegetable Science Scholar and persons interested in tomato improvement programme."
