  • Apomixis: Types and Advantages in Plant Breeding ( 58 reads)   

    Apomixis is a type of reproduction in which sexual organs of related structures take part but seeds are formed without union of gametes. Seeds formed in this way are vegetative in origin. Apomixis is widely distributed among higher plants. More than 300 species belonging to 35 families are apomictic. Here, a brief account of apomixis, is furnished only from the point of view of breeding. - Category: Agriculture
  • Seed Drying: Principle, Methods and their Advantages ( 91 reads)   

    Seed drying should reduce the seed moisture content to safe moisture limits to maintain its viability and vigour during storage, which may otherwise deteriorate quickly owing to mould growth, heating and enhanced microbial activity. Greater the seed moisture content lesser should be the drying temperature and vice versa. - Category: Agriculture
  • Varietal Deterioration: Causes and Maintenance ( 84 reads)   

    The genetic purity of a variety deteriorates due to several factors during the production cycles. Developmental variations, mechanical mixtures, mutations, natural crossing, minor genetic variations, selected influence of pest and diseases and techniques of the plant breeder are the main causes of varietal deterioration. It can be maintained using isolation, roguing, grow out tests etc. - Category: Agriculture
  • Quality Planting Material for Seed Spices - Higher Productivity ( 94 reads)   

    Without the use of good quality seed material, the investments incurred on fertilizers, pesticides and water will not pay dividend which ought to be realized. Seed spices are small to very small in size except coriander and fenugreek. Besides physical loss during sowing, processing and storage cumin, ajwain and celery are highly vulnerable to the loss of viability. - Category: Agriculture
  • Heterosis and Inbreeding Depression [PDF] ( 133 reads)   

    Heterosis is defined as the superiority of F1 hybrid over both the parents in terms of yield and/or some other characters. Cross pollinated species and species reproducing asexually are highly heterozygous. When these species are subjected to selfing or inbreeding they show severe reduction in vigour and fertility. This phenomenon is known as inbreeding depression. - Category: Agriculture
  • Fennel, Cumin and Ajwain: Medicinal Values and Uses ( 130 reads)   

    Seed spices like fennel, cumin and Ajwain, besides being important from home consumption point of view, are gaining increasing importance as medicinal articles. These are extensively used as flavouring agents in various food products and in pharmaceutical industry, especially in the preparation of Ayurvedic medicines. - Category: Agriculture
  • Drought Stress and its Effect in Plants ( 188 reads)   

    Agricultural drought is the lack of ample moisture required for normal plant growth and development to complete the life cycle. The main consequences of drought in crop plants are reduced rate of cell division and expansion, leaf size, stem elongation and root proliferation, and disturbed stomatal oscillations, plant water and nutrient relations with diminished crop productivity, and water use efficiency. - Category: Agriculture
  • Coriander and Fenugreek: Medicinal Values and Uses ( 147 reads)   

    Coriander and fenugreek are extensively used as flavouring agents in various food products and in pharmaceutical industry, especially in the preparation of Ayurvedic medicines. These seed spices are also used very frequently in homemade medicines for different ailments. - Category: Agriculture
  • Breeding for Insect Resistance ( 133 reads)   

    The breeding for insect resistance is most important because many crops in India and other countries are affected by various insects and it is necessary because it prevent from environmental pollution, the death of beneficial predators, the higher costs involved in spraying of various chemicals and for building up of resistance. - Category: Agriculture
  • Somaclonal Variation: Sources, Achievements and Advantages ( 134 reads)   

    Somaclonal variation includes aneuploids, sterile plants and morphological variants, sometimes involving traits of economic importance in case of crop plants. The usefulness of variation was first demonstrated through the recovery of disease resistant plants in potato (resistance against late blight and early blight) and sugarcane (resistance against eye-spot disease, Fiji disease and downy mildew). - Category: Agriculture
  • Selfing and Crossing Techniques in Plants ( 157 reads)   

    Selfing and crossing are the essential procedures in crop improvement process. The exact procedures used to ensure self or cross-pollination of specific plants will depend on the floral structure and normal manner of pollination. Removal of stamens or anthers or killing the pollen of a flower without the female reproductive organ is known as emasculation. - Category: Agriculture
