This contributed volume brings out a comprehensive collection of changes from cellular to molecular levels in medicinal plants under extreme environments. The focus of this book is to address the molecular changes in medicinal plants under different abiotic stresses. Medicinal plants are regarded as rich resources of components that can be used for drug development in the pharmaceutical industry. A few medicinal plants are considered vital sources of nutrients and solicited for their therapeutic properties. Therefore, it is essential to understand medicinal plants' interaction under abiotic stresses as compounds obtained from these plants play an important role in human health. This book is of interest to students, teachers, researchers, scientists, medicinal plant experts, and policymakers. Also, the book provides study material for undergraduate and graduate students of botany, environmental sciences, medicinal and aromatic plants, biochemistry, and biotechnology. National and international scientists working in the area of medicinal plants, drug development, and policymakers will also find this a useful read

African Marigold (Tagetes erecta L)is an important commercial flower of India, belonging to family Asteraceae. It is also known as friendship flower in the United States and represents vulgar minds. Easy cultivation and wider adaptability of the crop has increased its popularity . Flowers are sold in the market as loose flower or for making garlands, offering in temples, churches, festivals, beautification and landscape. Although marigold is a very important flower, yet very little research work had been done towards the crop improvement. It has a lot of variation with respect to growth and flower characters, which varies with germplasm. Germplasm serves as valuable natural reservoir in providing needed attributes for developing successful varieties. However, the extent of improvement depends upon the amount of variability in different characters present in the crops, which is an indispensable prerequisite for successful breeding programmes. Therefore, selection accordance to high GCV and PCV is more effective for a particular traits. High heritability alongwith high genetic advance in per cent of mean provides a best guiding to formulate effective selection programme.
