Review on Concept and Impact of Double Haploid Techniques in Crop Improvement (original) (raw)

Based on previous studies this review presents about double haploid technology and its role in crop improvement. Double haploids are plants those carry two sets of chromosomes that are created from the haploid plants. Different methods such as androgenesis (microspore or anther), gynogenesis (ovule or ovary) haploid inducer lines and wide crosses are used for developing haploid thereby double haploid. Though various chromosome doubling agents found, colchicine has been widely using. The successes of double haploid production relay on different factors like flower parts development stage, culture media, genotype, donor parent growth condition and haploid detection methods. This technology able shortens breeding cycle or time, complete genetic purity, efficient in genetic study, marker development, mutation and transformation better than traditional way of breeding. Generally, understanding DH technology has important contribution in accelerating breeding program for immediate reac...
