Improved Samba Mahsuri
Improved Samba Mahsuri (RP Bio-226) is a high yielding fine grain rice variety. In a collaborative project, scientists from CSIR-CCMB and the ICAR-Indian Institute of Rice Research (IIRR, erstwhile Directorate of Rice Research RR, worked together to develop it. The variety was developed using Marker assisted selection and has three major bacterial blight resistance genes Xa21, xa13 and xa5. All India Coordinated Rice Improved Project (AICRIP) conducted trails in multiple locations across India, and found positive results for resistance to bacterial blight.

Cereal
A cereal is any grass cultivated for the edible components of its grain (botanically, a type of fruit called a caryopsis), composed of the endosperm, germ, and bran. Cereal grain crops are grown in greater quantities and provide more food energy worldwide than any other type of crop and are therefore staple crops. They include wheat, rye, oats, and barley. Edible grains from other plant families, such as buckwheat, quinoa and chia, are referred to as pseudocereals. In their unprocessed whole grain form, cereals are a rich source of vitamins, minerals, carbohydrates, fats, oils, and protein. When processed by the removal of the bran and germ the remaining endosperm is mostly carbohydrate. In some developing countries, grain in the form of rice, wheat, millet, or maize constitutes a majority of daily sustenance. In developed countries, cereal consumption is moderate and varied but still substantial, primarily in the form of refined and processed grains. Because of ...

Marker Assisted Selection
Marker assisted selection or marker aided selection (MAS) is an indirect selection process where a trait of interest is selected based on a marker ( morphological, biochemical or DNA/RNA variation) linked to a trait of interest (e.g. productivity, disease resistance, abiotic stress tolerance, and quality), rather than on the trait itself.Ribaut, J.-M. et al., Genetic basis of physiological traits. In Application of Physiology in Wheat Breeding, CIMMYT, Mexico, 2001.Ribaut, J.-M. and Hoisington, D. A., Marker assisted selection: new tools and strategies.

Blight
Blight refers to a specific symptom affecting plants in response to infection by a pathogenic organism. Description Blight is a rapid and complete chlorosis, browning, then death of plant tissues such as leaves, branches, twigs, or floral organs. Accordingly, many diseases that primarily exhibit this symptom are called blights. Several notable examples are: * Late blight of potato, caused by the water mold ''Phytophthora infestans'' (Mont.) de Bary, the disease which led to the Great Irish Famine * Southern corn leaf blight, caused by the fungus '' Cochliobolus heterostrophus'' (Drechs.) Drechs, anamorph '' Bipolaris maydis'' (Nisikado & Miyake) Shoemaker, incited a severe loss of corn in the United States in 1970. * Chestnut blight, caused by the fungus ''Cryphonectria parasitica'' (Murrill) Barr, has nearly completely eradicated mature American chestnuts in North America. * Citrus blight, caused by an unknown agent, infects all citrus scions. * Fire blight of pome fruits, ...

Rice Varieties
This is a list of rice cultivars, also known as rice varieties. There are several species of grain called rice. Asian rice (''Oryza sativa)'' is most widely known and most widely grown, with two major subspecies (''indica'' and ''japonica'') and over 40,000 varieties. Also included in this list are varieties of African rice (''Oryza glaberrima'') and wild rice (genus ''Zizania''). Rice may vary in genetics, grain length, color, thickness, stickiness, aroma, growing method, and other characteristics, leading to many cultivars. For instance, over nine major rice cultivars exist to make sake alone. The two subspecies of Asian rice, indica and japonica, can generally be distinguished by length and stickiness. Indica rice is long-grained and unsticky, while japonica is short-grained and glutinous. Rice can also be divided based on processing type into the two broad categories of brown and white. Brown rice is whole grain, with only the inedible hull of the seed removed, while white ...
