Role of next generation breeding tools in climate resilient horticultural crops The recently developed new generation breeding tool Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR Associated 9 (CRISPR/Cas9) plays an important role in crop improvement due to its simplicity, high efficiency and accuracy compared to other existing molecular breeding tools. The discovery of CRISPR/Cas9 technology has made it possible to eliminate undesirable genes or introduce desired additional gene fragments, in addition to precisely modifying the genome by introducing single nucleotide changes आक्रमणकारी विदेशी डीएनए की प्रतिक्रिया में CRISPR-Cas9 प्रणाली की क्रिया को तीन चरणों में विभाजित किया जा सकता है: (i) अधिग्रहण चरण - आक्रमणकारी डीएनए की पहचान की जाती है और लक्ष्य डीएनए...

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...

गेहूँ सुधार के लिए डबल्ड हैप्लोइडी तकनीक: एक परिचय  Doubled haploidy technique is used to generate pure inbred lines for basic research and production of commercial cultivars. These lines are pure and genetically homozygous individuals are produced when spontaneous or induced chromosome duplication of haploid cells occurs. Double haploids are one of the biggest achievements in plant breeding because of production of completely homozygous plant within a year (Hooghvorst and Nogues., 2021). The production of doubled haploid lines can accelerate the breeding of new wheat varieties by several years through one step creation of 100% homozygous plants. This technology plays an important role in studying the genetic control of traits in wheat, marker...

फसल सुधार में जैव प्रौद्योगिकी की भूमिका कृषि भारतीय अर्थव्यवस्था का मूल आधार है, भारत की लगभग 65-70 प्रतिशत आबादी प्रत्यक्ष व अप्रत्यक्ष रूप से कृषि पर निर्भर है, लेकिन इस बदलते परिवेश में जहाँ बढ़ती आबादी के कारण कृषि जोत सिकुडती जा रही है, वहीं बदलती हुई जलवायुवीय परिस्थितियों ने कृषि स्थति को और भयावाह बना दिया है। कहीं पानी की कमी के कारण बुवाई पर रोक है, तो कहीं अधिक पैदावार की वजह से उपज की पर्याप्त कीमत नहीं मिल पा रही है। हरित क्रांति ने उपज तो बढ़ा दी है, लेकिन बदलते वक्त में खेती के सामने अलग चुनौतियां भी पैदा कर दी हैं। ऐसी खोज जरूरी है, जो...

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...
