A SIMPLE WHEAT HAPLOID AND DOUBLED HAPLOID PRODUCTION SYSTEM USING ANTHER CULTURE
|
SUMMARY
Wheat (Triticum aestivum L.) haploids and doubled haploids have been used in breeding programs and genetic studies. Wheat haploids and doubled haploids via anther culture are usually produced by a multiple step culture procedure. We improved a wheat haploid and doubled haploid production system via anther culture in which plants are produced from microspore-derived embryos using one medium and one culture environment. In the improved protocol, tillers of donor plants were pretr...

Rapid attainment of a doubled haploid line from transgenic maize (Zea mays L.) plants by means of anther culture
In Vitro Cellular & Developmental Biology
; SUMMARY We present a strategy for establishing a transgenic doubled haploid maize line from heterozygous transgenic material by means of anther culture. Compared to conventional inbreeding, the in vitro androgenesis technique enables a faster generation of virtually fully homozygous lines. Since

Inheritance of common bunt resistance in androgenetically derived doubled haploid and random inbred populations of wheat.
Crop Science
; An understanding of the inheritance of resistance to disease is valuable for planning crosses in breeding programs, identifying resistance genes, and developing genetic markers to assist in selection. However, genetic analysis of populations of [F.sub.2] plants or [F.sub.3] families segregating for

PLANT REGENERATION FROM RICE ANTHERS CRYOPRESERVED BY AN ENCAPSULATION/DEHYDRATION TECHNIQUE
In Vitro Cellular & Developmental Biology
; SUMMARY Anther-derived rice (Oryza sativa L., ssp. japonica variety Yerua P.A.) plants were obtained after cryopreservation by an encapsulation/dehydration technique. Immature anthers, excised from spikelets pretreated at 8C for 8d, were encapsulated in calcium alginate beads. The beads were

Crop Science
; TOCOPHEROLS ARE IMPORTANT natural antioxidants that inhibit fatty acid peroxidation in vegetable oils and act as free radical quenchers. Tocopherols contain a tocochromanol ring and exist in four forms ([alpha [beta [gamma and [delta]-tocopherol) differing in both molecular structure and biological

Critical Reviews in Plant Sciences
; The Fabaceae species have a major role to play in sustainable farming systems, but they have lagged behind other families in respect to the development of doubled haploid protocols for plant improvement. Currently, no plant improvement program uses doubled haploids on a routine basis for any member

CHARACTERIZATION OF PLOIDY LEVELS OF WHEAT MICROSPORE-DERIVED PLANTS USING LASER FLOW CYTOMETRY
In Vitro Cellular & Developmental Biology
; SUMMARY The purpose of this study was to determine simply and accurately ploidy levels as estimated by changes in nuclear DNA content of wheat (Triticum aestivum L.) plants regenerated from microspore-derived embryos. Using flow cytometry, the nuclear DNA content of green (83) and albino (222)

Performance of doubled haploid populations segregating for linolenic acid levels in spring rapeseed.
Crop Science
; Rapeseed is the third largest oil crop in the world. Rapeseed oil is considered one of the superior edible vegetable oils because of its low amount of saturated fatty acids. However, rapeseed and soybean oils are relatively high in linolenic acid (18:3) (80-120 g [kg.sup.-1] in seed oil) which,
