Rice is the major staple food crop of the world, providing about a quarter of the population’s calories and up to 75% of calories consumed by poor people ().Different varieties of rice are adapted to grow in many types of environments, in both temperate and tropical areas, in flood- and drought-prone areas, and in cool and warm regions (Yoshida, ).

  Acreage of rice had continued to increase until the s, and it showed the highest value with million. hectares in But then, it has gradually decreased. mainly due to the reduction policy on rice acreage, and acreage of rice shows almost half of the peak in the s. Land productivity of rice (kg/10a) was only or so up As an essential food for human beings, rice (Oryza sativa L.) has been widely consumed and planted around the ularly, 80% of rice production in the world comes from Asian countries [].More than half of the world’s population constantly includes rice in their diet, and about calories are provided by rice per person per day [].As world population growth and climate change are

Over the last few decades, the use of molecular markers has played an increasing role in rice breeding and genetics. Of the different types of molecular markers, microsatellites have been utilized most extensively, because they can be readily amplified by PCR and the large amount of allelic variation at each locus. Microsatellites are also known as simple sequence repeats (SSR), and they are   BREEDING BIOLOGY OF Channa punctatus (BLOCH) AND ITS REARING IN RICE FIELD ECOSYSTEM By Dr. AMULYA KUMAR SAIKIA (This work was submitted by SHRI AMULYA KUMAR SAIKIA as Ph.D. thesis in Department of Zoology, RAJIV GANDHI UNIVERSITY, RONO HILLS, ITANAGAR, ARUNACHAL PRADESH, INDIA in the year ) pdf.

As a result, Asia has been the continent with the fastest growth in fossil fuel consumption and consequently soaring emissions of greenhouse gases and ozone precursors (IPCC, ).

Submitted: October 17th Reviewed: March 14th Published: September 26th DOI: /intechopen This chapter provides details on recent developments in rice breeding programs around the globe for enhanced abiotic stress tolerance.

The list of major QTLs identified is provided for heat tolerance where molecular breeding at a large scale is yet to see the light of the :// This book presents the latest advances in rice genomics, genetics and breeding, with a special focus on their importance for rice biology and how they are breathing new life into traditional ://   Current breeding schemes and operations have been well described in the seminal and highly influential text book on rice breeding by Jennings, Coffman and Kauffman published in For example, IRRI’s irrigated breeding program has used a classical pedigree method since the establishment of the institute in the s [10].

These stresses can be caused by extreme climatic changes like drought, flooding, or rising sea levels. While some can be inherent like high iron toxicity in the soil. Our breeding programs aim to develop rice types that can survive in these harsh environments.

IRRI breeders use a breeding method known as marker-assisted ://   To take just a few examples, over 25% of the South Asian wet-season rice area is still planted to the variety Swarna, which was released about 35 years ago (IRRI, unpublished data).

In India, the average age of wheat varieties in farmers' fields increased from 9 years in to 13 in (Krishna et al., ). Because the time it takes The good news is that there is significant genetic variation for heat and drought/submergence tolerance in the global maize, wheat and rice gene banks.

Either through the application of conventional breeding or the use of new breeding techniques, this genetic diversity offers a way to ameliorate most of the immediate climate change ://   countries (LDCs) and small island developing States (SIDS) in particular need special consideration due to their extreme vulnerability.

In this book, background information on climate change and why adaptation is needed in developing countries is. At the moment, one of the most flood-threatened crops is rice. About 30% ( million) of people living in abject poverty (i.e., daily income less than 1 $) in Asian countries reside in flood-prone rice cultivating regions of South Asia, with Nepal, Bangladesh, and India accounting for half of the above-stated Nepal, 15% of the total cultivated areas of million hectare is   Breeding for biotic stresses.

Insect damage to irrigated rice is estimated to cause average yield losses of % (Litsinger et al., ).Losses range from 5% to 71% in upland rice (Litsinger et al., a) and from 2% to 88% in rainfed lowland rice (Litsinger et al., b).Reducing insect-mediated yield losses has been one of the important objectives of breeding programs in the post–Green   The sarus crane (Antigone antigone) is a large non-migratory crane found in parts of the Indian subcontinent, Southeast Asia, and tallest of the flying birds, standing at a height up to m (5 ft 11 in), they are a conspicuous species of open wetlands in south Asia, seasonally flooded Dipterocarp forests in Southeast Asia, and Eucalyptus-dominated woodlands and grasslands in
