Centres of Genetic Diversity

Centres of Genetic Diversity Introduction Centres of genetic diversity are geographical regions of the world where maximum genetic variation of plants or animals occurs .  These regions contain wild relatives, primitive cultivars, landraces, and domesticated varieties of species.  They play a crucial role in evolution, plant breeding, conservation of biodiversity, and food security. The concept of centres of genetic diversity is closely associated with N. I. Vavilov, a Russian geneticist, who studied crop plants extensively and proposed that crop domestication occurred in specific regions showing high variability. Definition A centre of genetic diversity is a region where: A species exhibits maximum genetic variability Both wild and cultivated forms are present Continuous natural selection and adaptation take place Vavilov’s Concept of Centres of Origin Vavilov (1926) proposed that: Cultivated plants originated from definite geographical areas These areas show greatest diversi...

PLANT INTROUCTION: TYPES AND PROCEDURE

PLANT INTROUCTION: TYPES AND PROCEDURE 1. Introduction Plant introduction is the transfer of plant species, varieties, or genotypes from one geographical area to another where they were not previously grown.  It is one of the oldest and most important methods of crop improvement and forms the basis of modern agriculture. Many important crops such as wheat, rice, maize, potato, cotton, sugarcane, and tobacco have been introduced from other countries. Definition : Plant introduction is the process of introducing plants or plant genetic material from their native or foreign regions into a new area for cultivation, evaluation, and utilization. 2. Objectives of Plant Introduction To increase crop productivity To introduce high-yielding varieties To obtain disease- and pest-resistant plants To introduce early maturing or drought-tolerant varieties To improve quality traits (oil content, protein, fiber, taste) To broaden the genetic base of crops To replace inferior local varieties To dev...

Source of germplasm

Sources of Germplasm   Introduction Germplasm refers to the total genetic resources of a crop species, including seeds, plant parts, tissues, pollen, or entire plants that carry hereditary material.  It is the basic raw material for plant breeding and crop improvement. The success of any breeding programme depends largely on the availability, diversity, and proper utilization of germplasm. 1. Landraces (Primitive Cultivars ) Landraces are locally adapted traditional varieties developed by farmers through natural and artificial selection over long periods. Characteristics: High genetic variability Adapted to local climate and soil Low yield but stable performance Importance: Source of resistance to pests, diseases, and abiotic stress Example: Traditional rice varieties of Kerala 2. Obsolete Varieties These are varieties once cultivated widely but later replaced by improved varieties. Importance: Possess useful genes lost in modern breeding Provide genetic diversity 3. Modern Cu...

Concepts of de Candolle and Vavilov

1. Concept of de Candolle (1882) Introduction Alphonse de Candolle, a Swiss botanist, proposed one of the earliest scientific ideas about the geographical origin of cultivated plants in his book “Origin of Cultivated Plants” (1882). Main Concept Cultivated plants originated in regions where their wild ancestors were naturally found. These regions are usually areas of ancient human civilization, where agriculture first developed. Basis of de Candolle’s Concept De Candolle used:(BAHL) Botanical evidence – presence of wild relatives Historical records – ancient literature and scriptures Archaeological findings Linguistic evidence – local names of crops Geographical distribution Key Features Emphasized broad geographical regions rather than precise centers. Believed domestication occurred over a long time. Recognized multiple origins for some crops. Examples Wheat → Near East Maize → Central America Potato → South America Rice → South-East Asia Merits First systematic scientific approach. ...

Sampling Method and Errors

Introduction In statistics and research, it is often not possible to study the entire population due to limitations of time, cost, and effort. Therefore, a sample is selected from the population to represent the whole. The method used to select this sample is called the sampling method.  While sampling makes research practical, it may also lead to errors, known as sampling errors. Sampling Method A sampling method is a procedure or technique used to select a subset (sample) from a population so that it represents the population accurately. Sampling methods are broadly classified into: Probability Sampling Methods Non-Probability Sampling Methods 1. Probability Sampling Methods In probability sampling, every unit of the population has a known and equal chance of selection. These methods are scientific and reliable. a) Simple Random Sampling Each member of the population has an equal chance of being selected. Selection can be done using lottery method or random number tables. Merits:...
