This germplasm diversity must be made up of wild species (high phenotypic variability) and cultivated species (elite cultivars). Fungi, bacteria, nematodes, insects and many other agencies cause untold havoc to agricultural output. To develop varieties with better characteristics, such as: 5. Climate-smart plant breeding objectives To meet climate evolution requirements, the breeder needs a broad genetic base. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. The harvest also becomes difficult. Sugarcane Breeding Institute (SBI), Coimbatore. Plant breeding uses principles from a variety of sciences to improve the genetic potential of plants. The development and maintenance of adequate national plant breeding capacity requires government policies that promote scientific, economic and social developments. Alphonse de Condolle in 1882 was the first to give an account of the history and origin of cultivated plants. 6. Another trait, that the plant breeder is constantly looking for in any plant are unusual features. Name the types of nitrogenous bases present in the RNA. TOS4.

Our mission is to provide an online platform to help students to discuss anything and everything about Essay. A successful breeding program should have clearly defined objectives that are realistic and based on the industry demand for the crop. Undesirable Effects of Crop Breeding for Crop Improvement 3. Many of the garden plants are highly prized for their shape, density, size, bright color of the flowers, early blooming or late blooming etc. Similarly the impact of coffee rust influenced plantations to switch over to Tea cultivation from coffee in Sri Lanka. Plant breeding is the purposeful manipulation of plant species to create desirable plant types that adapt to human needs more efficiently. Today plant breeding is a specialized technology based on genetics. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. Plant breeding objectives In early period (1960-1985), the main objective was to increase yield of main stable crops i.e. 6. Objectives. There are the following different types of … As a result many thousands of Irish people migrated to USA. 9. The objective of this paper is to discuss plant breeding methods as an evolving technology, considering the increasing levels of knowledge of the underlying mechanisms and the control of the process of generating and selecting superior plant types. Some well known achievements are development of semi-dwarf wheat and rice varieties, noblization of Indian canes (sugarcanes), and production of hybrid and composite varieties of maize, jowar and bajra. The quality of plants in terms of height, size or shape is another character sought after by the plant breeder. 10. To raise plants with desired characteristics. The height of the rice plant must be tall enough to provide a structure to support high yield as well as facilitate harvest, but not too tall to be susceptible to lodging. Let us make an in-depth study of the definition, objectives and historical background of plant breeding.
