Doubled Haploids versus Conventional Breeding in CIMMYT Wheat Breeding Programs
Doubled haploid (DH) technology has been used in breeding programs for several decades and is currently the method of choice in a number of crop species, including barley (Hordeum vulgare L.), rapeseed (Brassica napus L.), maize (Zea mays L.), and wheat (Triticum aestivum L.). In this study we investigated via computer simulation the benefit of using DHs compared with the conventional wheat bre...
متن کاملHaploids and Doubled Haploids in Plant Breeding
Haploids are plants (sporophytes) that contain a gametic chromosome number (n). They can originate spontaneously in nature or as a result of various induction techniques. Spontaneous development of haploid plants has been known since 1922, when Blakeslee first described this phenomenon in Datura stramonium (Blakeslee et al., 1922); this was subsequently followed by similar reports in tobacco (N...
متن کاملProduction and identification of doubled haploids in tropical maize.
The production of maize doubled haploid (DH) lines is a technique commonly used by private companies, but not by Brazilian public institutions. Research on this technique is essential to develop and improve the production of DH lines grown under tropical conditions. We assessed the ability of a gynogenetic haploid inducer system to induce haploids in a tropical environment, assessed the inducti...
متن کاملSNP Marker Assisted Selection for Identification of Fusarium Resistant Melon Plants
Melon is an important crop cultivated in moderate climate regions of the world. One of the most important diseases of this plant is vascular wilt caused by Fusarium oxysporum f.sp. melonis (Fom). Infection of farm by this pathogen can result in huge damage around the world. Development of resistant varieties is the most effective method for disease control. Four races of 0, 1, 2 and 1,2 have be...
متن کاملDevelopment of yellow rust resistant doubled haploid lines of wheat through wheat ´ maize Crosses
In order to produce doubled haploid lines of bread wheat resistant to strip or yellow rust, three F1 wheat hybrids were crossed using pollens of three maize hybrids. Out of 1071 pollinated florets, success in seed set ranged from 63.1% to 93.3% (mean 78%). Differences in seed set among the crosses were not significant. Embryo formation in the seeds developed on different crosses also varied fro...
