फसल सुधार में बायोमेट्रिक्स की भूमिका To create a significant hypothesis from plant data, statistical algorithm may be utilized. The biometric genetics is very useful to extract the significant information for crop improvement. The study of genetic variability within species and between species, relationship among the phenotypic traits, contribution of independent traits to dependent traits. All this exclusive information may derived by the help of biometrical techniques like analysis of variance, correlation study, path analysis, principal component analysis etc.     फसल सुधार में बायोमेट्रिक्स की भूमिका In the year 2010, the world’s population was estimated to be more than 6.8 billion people. The United Nations projects that the world population will surpass 7...

नैनोटेक्नोलॉजी: कृषि फसलों में फसल सुधार का एक आधुनिक दृष्टिकोण Nanofertilizers in agriculture aid in enhancing plant growth. The results of cutting-edge nanobiotechnological research include nanopesticides, nanoinsecticides, nanofungicides, and nanoherbicides, which are used to manage weeds in fields . Nanoparticles are being used in agriculture for crop improvement in various crops in various crops. नैनोटेक्नोलॉजी: कृषि फसलों में फसल सुधार का एक आधुनिक दृष्टिकोण More than two thirds of the Indian population depends on agriculture for their livelihood, which has probably an impact on the Indian economy. But the Indian agricultural system was not as robust as it is now, either before or after independence.   Green Revolution, which employed some contemporary farming techniques, was...

फसल सुधार के लिए विकिरण उपयोग दक्षता का दोहन The energy of the entire ecosystem is reliant on the sun, which is the sole source of energy for all living organisms, directly or indirectly. Solar radiations reach from sun to earth and helps in photosynthesis, a process by which plants transform light energy into chemical energy. The rate of accumulation of dry matter of all plants is completely dependent on the interception of light energy from the sun (400–700 nm wavelength range), known as photosynthetically active radiation (PAR). Global climate changes are affecting crop yield potential and reducing the yield of crop significantly. A rapid rise in population is expected in the near...

फसल सुधार में पादप आनुवंशिक संसाधनों के प्रभावी उपयोग के लिए पूर्व प्रजनन Plant breeding is an art, science and technology of improving genetic makeup of plants for the benefit of humankind. The genetic diversity of crop plants is the foundation for the sustainable development of new varieties for present and future challenges which arises due to the various biotic and abiotic stresses. Genetic diversity provides an option to farmers and plant breeders to develop new and more productive crops / varieties through selection, hybridization and breeding, that are resistant to virulent pests and diseases and adapted to changing environmental conditions. Pre-breeding is necessary for making the germplasm usable in traditional breeding. It...

फसल सुधार के माध्यम से जैव संवधर्न की भूमिका Plants are the prime source of essential minerals nutrients. These mineral elements which play vital role for human beings for their existence and the continuity race of life. Some plants are rich for some mineral and have deficiency to the other. No plant alone that contain all mineral elements in efficiently for human beings from the earth. Deficiency of mineral is also called as ‘Hidden hunger’, results in poor growth and compromised psychomotor development of children, reduced immunity, exhausted, fatigue, irritability, weakness, hair loss, wasting of muscles, sterility, morbidity and demise (Stein, 2010). Conventional breeding and genetic engineering techniques are the two approaches that may...

फसल सुधार के लि‍ए फसलों में सूक्ष्मप्रजनन  Various methods of tissue culture and molecular biology have shown tremendous potential for creation, conservation and precise characterization of genetic variability for improvement of fruit, field, forest crops, medicinal and aromatic plants. Micropropagation of crops is now one of the best and most successful examples of the commercial application of tissue culture technology. Propagation of plants from very small plant tissues/ parts under in vitro conditions in the laboratory is called micropropagation. Commercial application of tissue culture started in 1970 in USA with the micropropagation of orchids. Since then it has seen tremendous expansion globally both in terms of number of production units and...
