Culinary melon also known as non dessert cucumber(Cucumis melo subsp. agrestis var. acidulus)belongs to the family Cucurbitaceae. It is widely cultivated in Southern parts of Indian subcontinent. It is mainly utilized for preparation of lentil soup, sambar, dosa, palya and chutney. 70 accessions were collected from six South Indian states namely Karnataka, Kerala, Andhra Pradesh, Tamil Nadu, Telangana and Goa. The accessions were evaluated for incidence of downy mildew resistance during Kharif 2018 under natural condition. The percent disease index (PDI) for downy mildew ranged from 3.70 to 48.64%. 10 accessions showed resistance to downy mildew. Among them, accession MS21 showed resistance with average least PDI of 3.70 followed by MS 6 (6.54). 50 accessions were found to be moderately resistant with average PDI ranging from 20 to 39.80. 12 accessions were found susceptible with PDI ranging from 41 to 49. None of the accession was found highly susceptible to the disease. The resistant accessions can be utilized as donor parents for resistant breeding in the improvement of culinary melon as well as melon group of vegetables.

Overview
The present book on Plant Anatomy depicts anatomical aspects of the plant that will help a reader for basic understanding in the evolution of different plant communities. It plays an important role for adaptation of plant to different biotic and abiotic stress. It has been documented that some glands, trichomes, epicuticular wax are resistant to insect pests. Similarly, the presence of trichomes epicuticular wax, compactly arranged palisade tissue, collenchyma and sclerenchyma induces drought resistance. So it is necessity of all scientists, especially for breeder, plant physiologist to have the thorough knowledge on plant anatomy for the selection of adaptable cultivars and also for better management of crops. This book covers all the aspects of internal structures of plant with its high resolution microscopic images and drawings of plant parts. The anatomical studies of plants organs are being presented here, as we believe that the morphological characters alone cannot project the adaptations in the plant. They can be better understood when supplemented with the anatomical characteristics, unique to individual type of crop. This text book would be of great help to faculties and scholars in plant as well as agricultural sciences and scientific communities in general as a good source of information and references
As per the Veterinary Council of India (VCI) syllabus, accounting is a part of BVSc & AH course in the discipline of extension education. However, there is a dearth of text book on this course written or verified by an expert in accounting.This book is expected to fill this gap. The book consists of seven chapters covering the VCI-syllabus on accounting with exercise, and summary at the end of each chapter. Besides, glossary and model questions covering all chapters with answers to the objective questions are appended to the end of the book. The book may not only benefit the students pursuing BVSc&AH degree but also the teachers engaged in the teaching of the course in veterinary colleges and universities in India. Besides, the farm businessmen and those interested in accounting may also find the book useful.

Overview
The present book, Botany of Vegetable Crops, is different from other books on vegetable crops. It contains 12 chapters with emphasis on major vegetable crops like Tomato, Chilli, Egg plant / Brinjal, Okra / Bhendi, Water melon, Bottle gourd, Bitter gourd, Cucumber, Ridge gourd, Sponge gourd, Cabbage and Coriander. It discusses on the morphology and anatomy of a few common vegetable plants. Morphological characters help in identifying the plant. It also gives an idea of the different adaptive modifications in the plant. It even mirrors the habitat, the climatic conditions under which it can be cultivated. The anatomical studies of each of the vegetable plant are also being presented here as we believe the morphological characters alone cannot project the adaptations in the plant. They can better be understood when supplemented with the anatomical characteristics unique to individual type of crop. Glossary added in this book can help readers to understand some related terminologies and bringing clarity of the content. We expect that this book would be of great help to a student of plant sciences, to a research scholar for reference and a good source of information, to a plant breeder, and to the scientific community in general.

Overview
The book is the compilation of comprehensive study of vegetable and tuber crops Worldwide. In the changing scenario of climate, it is well understood that merely agronomic management practices starting from sowing to nutrient, water, pest and disease management will not be able to produce potential harvest. In present days, growth limiting factors like drought, heat, cold shock, chilling stress, salinity, metal stress, allelopathy have posed alarming threat against successful crop production. So, physiological basis of crop growth and productivity must be well versed to formulate appropriate counter measures to overcome such constraints. Moreover, the productivity of the crop is guided by various physiological processes like efficient seedling growth, photosynthesis and translocation of photosynthates, sucrose accumulation, growth regulators, ABA, ethylene, brassinoid and balanced mineral nutrition etc. Authors have tried to concentrate all these aspects in lucid manner reviewing the up-to-date research investigation. The book widely covers solanaceous crops like chilli, potato, tomato and eggplant; cucurbit vegetables- squash, pumpkin, cucumber, bottle gourd, bitter gourd, muskmelon and watermelon; cole crops- spinach, coriander, parsley, celery, lettuce; root and tuber crops- carrot, turnip, beet root, radish, turmeric, colocasia, cassava, yam, sweet potato; bulb crops- onion, garlic, leeks; leguminous crops- cluster bean, snap bean, green peas, broad bean; other crops like okra, sparagus, shallot, rhubard. It will definitely be a rare book to the global readers.

The book Research Advances in Vegetable Crops is an outstanding contribution of the authors in the field of advancement of the vegetable researches all over the World. The book entitles from the seed germination and its necessity of establishment in the new environment where physiological responses are influenced by both biotic and abiotic factors. Priming is a simple technique that not only helps in proper germination but aid in seedling establishment. Phonotypical and physiological responses of different vegetable crops are of significant importance in relation to factors like nutrients, salinity, disease-pest attacks. Physiological and biochemical basis of tolerance to salinity is very important that may help in the evaluation and selection of pipeline hybrids and parents lines using a novel technique. Biotic factors are major constraints in crop production, so proper management strategies and control measures must be taken for potential outcome. In this book, a special emphasis was given on food value and food chemistry of different vegetable crops. Major aspects like nutritional value of fresh vegetable as well as food value, post-harvest physiology and processing, storage and food quality, medicinal values, food chemistry and food biotechnology have been discussed in lucid manner. Further, research advances in biotechnology of different crops will guide authors in formulating the direction of future research.
