Ebook "Biotechnology of crucifers" despite the recent advances made in the improvement of crucifer crops using conventional breeding techniques, the yield levels and the oil and meal quality could not be improved as expected. The understanding of genetic material (DNA/RNA) and its manipulation by scientists has provided the opportunity to improve crucifers by increasing its diversity beyond conventional genetic limitations.

Plant height is a prime example of a dynamic trait that changes constantly throughout adult development. In this study we utilised a large triticale mapping population, comprising 647 doubled haploid lines derived from 4 families, to phenotype for plant height by a precision phenotyping platform at multiple time points.

Artificial synthesis of octoploid rapeseed double haploid (DH) induction lines Y3380 and Y3560 was made possible by interspecific hybridization and genome doubling techniques. Production of pure lines by DH induction provides a new way to achieve homozygosity earlier in B.napus.

Two-line hybrid wheat system using thermo-photo sensitive genic male sterility (TPSGMS) is currently the most promising approach for wheat heterosis utilization in China. However, during past 20 years only few TPSGMS lines were developed in hybrid wheat breeding, which has been the main limiting factor to create heterotic hybrids.

Physcomitrella patens, a haploid dominant plant, is fast becoming a useful molecular genetics and bioinformatics tool due to its key phylogenetic position as a bryophyte in the post-genomic era. Genome sequences from select reference species were compared bioinformatically to Physcomitrella patens using reciprocal blasts with the InParanoid software package.

Mapping centromere locations in plant species provides essential information for the analysis of genetic structures and population dynamics. The centromere’s position affects the distribution of crossovers along a chromosome and the parental heterozygosity restitution by 2n gametes is a direct function of the genetic distance to the centromere.

Pyropia haitanensis is one of the most economically important mariculture crops in China. A high-density genetic map has not been published yet and quantitative trait locus (QTL) mapping has not been undertaken for P. haitanensis because of a lack of sufficient molecular markers.

Microspore embryogenesis describes a stress-induced reprogramming of immature male plant gametophytes to develop into embryo-like structures, which can be regenerated into doubled haploid plants after whole genome reduplication. This mechanism is of high interest for both research as well as plant breeding.

Sporophytic plants having gametophytic chromosome number are termed as haploid. These plants can be produced either spontaneously in nature or by in vitro or in vivo induction technique. By doubling chromosome number of haploid either spontaneously or artificially, double haploid (DH) could be produced. Double haploid are homozygous and this homozygosity is achieved in one generation by using DH production systems. This production system is used for fixation of heterosis. Genetic map construction is relatively easy with DH population.

Anther Culture or microspore culture is a very important and useful tool in plant breeding for efficient production of haploids and subsequent doubled haploid plants in many species, limited research has been conducted with Brassica –rapaas it is more recalcitrant in cell and tissue culture than other Brassicas. In order to access the effect of genotype on microspore embryogenesis in B –rapa, two high yielding brown Sarsoon cultivars (KS-101 and KOS-1) were studied for their response to haploid plant regeneration through Anther culture. Flower buds of 2.2 mm to 2.

In vivo haploid induction (HI) based on Stock6-derived inducer lines has been the most prevalent means of producing haploids. Nevertheless, the biological mechanism of HI is not fully understood, the twinembryo kernels had been found during haploid induction, which may provide potential evidence for the abnormal double fertilization during HI.

Liquid Murashige and Skoog (MS) medium in varying strengths, is the most commonly utilized medium for proficient rooting in the regenerated plants in doubled haploidy breeding protocols. On the other side, CPV (cocopeat: perlite: vermiculite) medium is currently being used in hardening of tissue culture regenerated plants.

Marigold is an important ornamental plant grown as garden plant and for flower decoration. It has been recognized as a key source of carotenoids; exclusively used in Pharmaceutical industries and poultry feed additives. However, improvement of this valuable species is hampered by its high heterozygosity, but presently the greatest emphasis is on development of haploids through ovary culture, the efficient and timesaving technique in varietal improvement.
