Standard text books are written with a purpose of giving a complete and detailed knowledge of a subject, but it is quite difficult for anyone to revise thoroughly on a day before the exams. We also felt the same during our examinations. The present book is primarily designed to cater to the requirements of aspirants appearing for ICAR JRF/SRF,NET, SAUs and all other competitive examinations in agriculture faculty. The book is prepared strictly according to the latest pattern of examinations conducted by the ICAR, New Delhi for awarding of JRF/SRF and offering admission in P.G and Ph.D professional degree programmes. The book presents comprehensive treatment of genetics and plant breeding, plant pathology, seed technology, plant genetic resources, agricultural microbiology and general agriculture besides presenting “How to crack ICAR JRF examination”. The latest trend of education is teaching through multiple choice questions. The multiple choice questions are intended to enable students to prioritize and plan their learning through regular practice. The book contains 25 mock tests of 3000 MCQs covering all aspects of plant sciences as well as general agriculture and additional information in the form of 20 appendices. The contents have been so designed as to include the syllabus of plant sciences. Students are advised to solve the question papers on their own and check their answers.
