FACTORS AFFECTING EMBRYOGENESIS IN MICROSPORE CULTURES OF BROCCOLI (Brassica oleracea var. italica) [PDF]

Journal of Plant Production, 2009
          Microspore culture is a very important and useful tool in plant breeding for haploid production and has been developed for many years. Broccoli (Brassica oleracea var. italica) is an important vegetable crop.

High Frequency Production of Doubled Haploid Rapeseed Plants by Direct Colchicine Treatment of Isolated Microspores

浙江大学学报. 农业与生命科学版, 2000
Techniques for microspore culture of Brassica napus have been improved rapidly, and embryogen-esis has been achieved in a wide range of genotypes. Plants regenerated from microspore-derived embryoids can be haploid, diploid or polyploid.

Chromosome doubling of microspore-derived plants from cabbage (Brassica oleracea var. capitata L.) and broccoli (Brassica oleracea var. italica L.)

Frontiers in Plant Science, 2015
Chromosome doubling of microspore-derived plants is an important factor in the practical application of microspore culture technology because breeding programs require a large number of genetically stable, homozygous doubled haploid plants with a high ...

Efficiency of three haplomethods in durum wheat (Triticum turgidum subsp. durum Desf.): isolated microspore culture, gynogenesis and wheat × maize crosses

Czech Journal of Genetics and Plant Breeding, 2019
This study presents the first report comparing the efficiency of microspore culture, gynogenesis and durum wheat × maize crosses for haploid plant production from three durum wheat genotypes (Razzek, Karim and Jneh Khotifa).

Effects of Genotype and Culture Conditions on Microspore Embryogenesis and Plant Regeneration in Brassica Rapa ssp. Rapa L.

Plants, 2020
Turnip is a biennial crop and, consequently, the creation of pure lines for breeding is a time-consuming process. The production of pure turnip lines using doubled haploids produced in isolated microspore culture has not been sufficiently developed.

Effect of ovary induction on bread wheat anther culture: ovary genotype and developmental stage, and candidate gene association.

Frontiers in Plant Science, 2015
Ovary pre-conditioned medium and ovary co-culture increased the efficiency of green doubled haploid plant production in bread wheat anther culture. The positive effect of this medium led to a 6- and 11-fold increase in the numbers of embryos and green ...

Efficient Production of Doubled Haploid Plants through Microspore Culture in Brassica napus

浙江大学学报. 农业与生命科学版, 2000
Since haploid embryoids were first obtained from microspore culture of Brassica napus there has been a rapid progress in the application of this technique in genetic studies and breeding utilization of rapeseed.

Impact of Ionic Liquids on Induction of Wheat Microspore Embryogenesis and Plant Regeneration

Agronomy, 2020
Ionic liquids are novel compounds with unique chemical and physical properties. They can be received based on synthetic auxins like 2,4-dichlorophenoxyacetic acid or dicamba, which are commonly used hormones in microspore embryogenesis.

Transcriptomics integrated with metabolomics reveals the effect of cold stress on rice microspores

BMC Plant Biology, 2023
Background Microspore culture is one of the important biotechnological tools in plant breeding. The induction of microspore embryogenesis is a critical factor that affects the yield of microspore-derived embryo productions.

Advancing Thermotolerance in Beans: Integrating Physiology, Genomics, and Breeding for Climate Adaptation

Legume Science, Volume 8, Issue 3, September 2026.
ABSTRACT Rising global temperatures increasingly threaten bean production and the food security of millions of people who depend on these protein‐rich legumes. Heat stress during the reproductive stages induces pollen sterility, flower abscission, and disruptions in source–sink relationships, resulting in yield losses of 30%–40% or more when critical ...
