The first part of this book Principles of Vegetable Breeding has been structured with 17 chapters detailing history of vegetable breeding, origin and domestication, reproductive features and pollination control mechanisms, general breeding methods for sexually and asexually propagated crops, breeding for high temperature stress, disease resistance and product quality, heterosis breeding, mutation breeding, breeding through alteration of ploidy, ideotype breeding, procedure for release of a variety, intellectual property rights and biotechnological approaches for vegetable breeding. The second part Practices of Vegetable Breeding has been framed on the details of 24 vegetable crops under all the reproductive feature group pertaining to their origin, taxonomy, distribution, crop botany and floral biology, reproductive behaviour, genetics of important traits with published gene list, breeding objective, germplasm resource, breeding methods and breeding achievement highlighting the released varieties of the public sector. Important references have been provided at the end of each chapter which will be helpful for the post graduate and doctoral level students. This book follows the syllabi prescribed by ICAR for B. Sc. Hons. (Ag.), B. Sc. Hons. (Hort.), M. Sc (Ag.), M. Sc (Hort.) and Doctoral degree programmes in Vegetable Science particularly Genetics and Breeding of vegetable crops. Authors long experience acquired through teaching and research on different aspects of vegetable breeding was put together to structure this book.

Dans la pr sente tude, 14 lign es parentales pr sentant des divergences dans diff rents caract res ont t crois es pour produire 23 hybrides F1. L'expression de six caract res morphologiques, savoir le port, la forme et la couleur des feuilles, la forme du fruit, l'extr mit de la fleur du fruit, la couleur du fruit m r avant le stade de rotation et les nervures la surface du fruit, a t tudi e. En outre, le poids du fruit, le diam tre quatorial, le diam tre polaire du fruit, l' paisseur du p ricarpe et le nombre de locules par fruit ont galement t tudi s chez les hybrides. L' tendue de la manifestation de l'h t rosis dans les hybrides pour les diff rents caract res des fruits a t analys e en r f rence la divergence g n tique et aux performances en soi des parents. La situation a t examin e en r f rence aux 4 hybrides les plus performants de cette tude, savoir BCT-109xBCT-115, BCT-82xBCT-110, BCT-90 x BCT-110, BCT-90 x BCT-109, qui ont manifest une h t rosis lev e pour la plupart des caract res des fruits. Performance per se des parents Les hybrides les plus performants en termes de manifestation de l'h t rosis pour les cinq caract res sont issus de combinaisons crois es Medium x Low ou Medium x High en ce qui concerne la performance per se des parents.

In der vorliegenden Untersuchung wurden 14 Elternlinien, die in verschiedenen Merkmalen voneinander abweichen, gekreuzt, um 23 F1-Hybriden zu erzeugen. Die Auspr gung von sechs morphologischen Merkmalen, n mlich Wuchsform, Blattform und -farbe, Fruchtform, Bl tenende der Frucht, Farbe der reifen Frucht vor dem Drehen und Rippung auf der Fruchtoberfl che, wurde untersucht. Au erdem wurden Fruchtgewicht, quatorialdurchmesser, Polardurchmesser der Frucht, Dicke des Perikarps und Anzahl der Loci pro Frucht bei den Hybriden untersucht. Das Ausma der Manifestation von Heterosis in den Hybriden f r verschiedene Fruchtmerkmale wurde unter Bezugnahme auf die genetische Divergenz und die Leistungen der Eltern analysiert. Die Situation wurde in Bezug auf die vier Spitzenhybriden dieser Untersuchung untersucht, n mlich BCT-109 x BCT-115, BCT-82 x BCT-110, BCT-90 x BCT-110, BCT-90 x BCT-109, die f r die meisten Fruchtmerkmale eine hohe Heterosis aufwiesen. Die leistungsst rksten Hybriden in Bezug auf die Manifestation der Heterosis f r alle f nf Merkmale stammen entweder aus einer Kreuzung mit mittlerer x niedriger oder mittlerer x hoher Leistung der Eltern.

Nella presente indagine sono state incrociate 14 linee parentali che mostravano divergenze in diversi caratteri per produrre 23 ibridi F1. Negli ibridi stata studiata l'espressione di sei caratteri morfologici: portamento della crescita, forma e colore delle foglie, forma del frutto, estremit del fiore del frutto, colore del frutto maturo prima dello stadio di rotazione e nervature sulla superficie del frutto, oltre a ci sono stati studiati il peso del frutto, il diametro equatoriale, il diametro polare del frutto, lo spessore del pericarpo e il numero di loculi per frutto. L'entit della manifestazione dell'eterosi negli ibridi per i diversi caratteri del frutto stata analizzata con riferimento alla divergenza genetica e alle prestazioni di per s dei genitori. La situazione stata esaminata con riferimento a 4 ibridi di prim'ordine in questa indagine, ossia BCT-109xBCT-115, BCT-82xBCT-110, BCT-90 x BCT-110, BCT-90 x BCT-109, che hanno manifestato un'elevata eterosi per la maggior parte dei caratteri del frutto. Per quanto riguarda le prestazioni dei genitori, gli ibridi pi performanti in termini di manifestazione dell'eterosi per tutti e cinque i caratteri sono stati generati da combinazioni incrociate medio-basse o medio-alte rispetto alle prestazioni dei genitori.

Na presente investiga o, foram cruzadas 14 linhas parentais mostrando diverg ncias em diferentes caracteres para produzir 23 h bridos de F1. Foram estudadas a express o de seis caracteres morfol gicos, nomeadamente, h bito de crescimento, forma e cor da folha, forma da fruta, extremidade da flor da fruta, cor da fruta madura antes do est gio de viragem e nervura na superf cie da fruta, al m deste peso da fruta, di metro equatorial, di metro polar da fruta, espessura do pericarpo, locula no. por fruta foram tamb m estudados nos h bridos. A extens o da manifesta o da heterose nos h bridos para diferentes caracteres de fruta foi analisada com refer ncia diverg ncia gen tica e aos desempenhos per se dos pais. A situa o foi examinada com refer ncia a 4 h bridos de topo nesta investiga o, a saber, BCT-109xBCT-115, BCT-82xBCT-110, BCT-90 x BCT-110, BCT-90 x BCT-109 que manifestaram uma heterose elevada para a maioria dos caracteres do fruto.

This book has been created to meet the needs of undergraduate and graduate students at State and Central Agricultural Universities studying vegetable science and horticultural science. The book offers an extensive overview of environmental and growth factors, seedling and graft production, nutrient and water management, organic and protected farming, crop protection, and post-harvest management of vegetable crops. In addition, the book provides detailed information on 42 major and minor vegetable crops grown in the tropical and subtropical regions, including their origin and taxonomy, importance and uses, botany, nutritional and medicinal values, and plant protection measures and post-harvest management. The authors extensive experience in teaching and research on various aspects of vegetable science at a State Agricultural University was leveraged in developing this book.

This publication offers a comprehensive overview of the classification of various vegetable crops and the fundamental principles of crop management practices, including seedling management, water management, plant nutrient management, pollination management, integrated pest management (IPM) techniques, disease management, and modern production technologies for 29 important vegetable crops. The books distinctive feature is its 190 color photographs, which illustrate four critical aspects of vegetable production, namely nursery management, physiological disorders, diseases, and insect pests of different vegetable crops. This book serves as an essential resource for students, faculty members, and technical personnel in colleges and universities, commercial vegetable farms, and extension and development officers, as well as nutritionists and dieticians in the field of vegetable science. It is the latest addition to the teaching and demonstrative field, providing extensive photographic documentation to aid in understanding and application of modern vegetable production technologies.
