Available in PDF, EPUB and Kindle. Book excerpt: When trying to solicit authors for this book it became apparent that the causal factors for heterosis at the physiological and biochemical level are today almost as obscure as they were 30 years ago. Though biometrical-genetical analyses point to dispersion of complementary genes - not overdominance - as the major cause of the phenomenon, plant breeders' experience still suggests a cautious, pragmatic approach to the dominance-overdominance controversy in breeding hybrid cultivars. Thus we are faced with a striking discordance between our limited comprehension of the causal factors and mechanism of heter osis on the one hand, and the extensive agricultural practice of utiliza tion of hybrid vigor on the other. Such utilization is the result of the economic value of hybrid combinations displaying superior yields and qualities as well as stability of performance, of benefits derived in breeding programs, and of the enhanced varietal protection of proprietary rights. No comprehensive and critical analysis of the phenomenon of heterosis in economic plants has been published for the last three decades since the now classical book Heterosis, edited by J . W. Gowen (Iowa State College Press, Ames, Iowa, 1952). The present book attempts to fill the gap and to assess the status of our present knowl edge of the concept, the basis, the extent, and the application of heterosis in economic plants.

This book was released on 2014-02 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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."

This book was released on 2019-05-23 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present investigation was carried out to study the magnitude of per se performance, heterosis and combining ability for fruit yield, its related component traits and quality in tomato. The experimental material consisting of 11 parents (3 females and 8 males), its 24 hybrids produced through Line × Tester mating design and standard check (Abhinav). The experiment was laid out in a randomized block design with 3 replications at Regional Horticultural Research Station, Navsari Agricultural University, Navsari, during late kharif 2015. The data were obtained for 23 characters including fruit yield, its components and quality traits.

This book was released on 2010-01 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Study was carried out at Palampur and Bajaura in India.7 lines, 4 testers & their 28 hybrids were evaluated in RBD with 3 replications in line x tester mating design. ANOVA revealed significant differences among genotypes and GxE interactions, the line x tester analysis revealed significant differences due to line x location, tester x location & line x tester x location interactions (tested against error mean squares) at both locations and pooled analysis for most of the traits. GCA effects revealed that the lines BT-18 and Rodade and tester Hawaii-7998 and EC-392698 at Palampur;lines BL-333 and CLN-2123 and testers EC- 191536 and EC-392698 at Bajaura were good general combiners for yield and its contributing traits. However, BT-18 and BL-333 among lines and EC-392698 and Hawaii-7998 among testers were good general combiners for maximum traits studied in over all pooled analysis. Based on combing ability, heterosis and mean performance, crosses BT- 18xHawaii-7998, RodadexEC-392698 and BL-333xEC- 191536 in overall pooled analysis had great promise for further exploration. Preponderance of non additive gene action was fond in most of the traits.

Download or read book Heterosis Combining Ability and QTL Analysis in Tomato written by Mofidul Hannan and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
