what is haploid plants?mention purpose of production of haploid plants in modern cultivation.

 Plant breeding is the art and science of changing the genetics of plants in order to produce desired characteristics.[1] Plant breeding can be accomplished through many different techniques ranging from simply selecting plants with desirable characteristics for propagation, to more complex molecular techniques (see cultigen and cultivar).

Plant breeding has been practiced for thousands of years, since near the beginning of human civilization. It is now practiced worldwide by individuals such as gardeners and farmers, or by professional plant breeders employed by organizations such as government institutions, universities, crop-specific industry associations or research centers.
International development agencies believe that breeding new crops is important for ensuring food security by developing new varieties that are higher-yielding, resistant to pests and diseases, drought-resistant or regionally adapted to different environments and growing conditions.

The plants which orginate from unfertilize egg cells in nature is called haploid plants.The are completly sterile and are otherwise useless but in modern cultivation it is higly useful for the imporvement of many crop plants.The haploid plants can be converted in to perfect homyzygous individuals in 2-3 years by colchicines treatment.Culture condition also induce diploidy in many cases.Because of their homozygosity double haploid plants are used extensively in crop improvment mutation study and study of effect of alleles.The tachnique is also intregated into breeding programmes.These plants are also screnned for isolating superior homozygous lines.The ones which have superio traits used to develop new varieties.

Haploid plants are the plants possessing only a single set of chromosomes in the sporophyte.
Haploid cells are produced from pollen or egg cells or from other cells of the gametophyte, then by induced or spontaneous chromosome doubling, a doubled haploid cell is produced, which can be grown into a doubled haploid plant.
In vitro production of haploids is of great significance in plant breeding programmes. By the process of androgenesis to produce haploids, followed by chromosome doubling, it is possible to develop exclusive male plants. The male plants are particularly useful when their productivity and applications are much more than female plants. Disease resistance genes can be introduced while producing haploids.

Which type of plants get a half number of chromosome means [( n- number of chromosome (23)] is called haploid plant. Haploid plant gives more nutration , improve ment and growth tous

Haploid plant are the those plants which have single set of chromosome in the sporophyte. haploid plants are improve the crop variety and gives nutrient to the soil.
