Effects of Colchicine on Populus canescens Ectexine Structure and 2n Pollen Production [PDF]

open access: yesFrontiers in Plant Science, 2020
Triploid breeding is a central way to improve growth traits, timber quality, and stress resistance in Populus. In the present study, the morphology and viability of colchicine-induced 2n pollen, triploid production by crossing induced 2n pollen, and ...

The strong competitive role of 2n pollen in several polyploidy hybridizations in Rosa hybrida [PDF]

open access: yesBMC Plant Biology, 2019
Background 2n pollen play a strong competitive role in hybridization and breeding of multiploids in Rosa hybrida. The ploidy inheritable characteristic of ‘Orange Fire’ × ‘Old Blush’ were analyzed.

Colchicine induction of ‘Old Blush’ 2n pollen for the hybridization and breeding of tetraploid rose [PDF]

open access: yesPeerJ, 2021
Obtaining 2n pollen from the diploid Chinese old rose ‘Old Blush’ through artificial induction is one important means of hybridizing and breeding modern tetraploid roses.

Induction of 2n pollen with colchicine during microsporogenesis in Phalaenopsis. [PDF]

open access: yesBreed Sci, 2022
The induction of 2n pollen is an important technique for breeding polyploid plants. Here, we observed meiosis in the pollen mother cells (PMCs) of six Phalaenopsis cultivars and attempted to induce 2n pollen. The meiotic stage was related to flower bud length. During meiosis, Phalaenopsis cultivars with flower widths of approximately 20-40 mm and 50-60

Analysis of Meiotic Behavior and 2n Pollen Formation Frequency in Triploid Hybrids of Chinese Jujube [PDF]

open access: yesPlants
The Chinese jujube (Ziziphus jujuba Mill.), an economically significant fruit tree native to China, is valued for both fresh and dried uses. In plants, 2n gametes serve as the fundamental basis for creating a sexual polyploid germplasm.

Genetic composition and heterozygosity of gibberellin-induced 2n gametes evaluated by SSR markers in Populus [PDF]

open access: yesBMC Plant Biology
Background The artificial induction of unreduced (2n) gametes, due to first division restitution (FDR) or second division restitution (SDR), is an important method to produce triploids in higher plants.

ClPS1 gene-mediated manipulation of 2n pollen formation enables the creation of triploid seedless watermelon [PDF]

open access: yesMolecular Horticulture
Seedless watermelons are increasingly dominating the consumer market due to their convenience and high quality. However, traditional triploid watermelon breeding faces challenges such as long breeding cycles and low survival rates of triploid F1 progeny,

Male fertility restoration of tetrad pollen sterility in BC1 and its derived populations from Solanum verrucosum [PDF]

open access: yesBMC Plant Biology
Background Tetrad sterility-type cytoplasmic male sterility (T-CMS) is characterized by sterile pollen grains that stick together to form a tetrad-like structure (tetrad pollen).

Cytomictic Anomalous Male Meiosis and 2n Pollen Grain Formation in Mertensia echioides Benth. (Boraginaceae) from Kashmir Himalaya [PDF]

open access: yesThe Scientific World Journal, 2014
Presently Mertensia echioides Benth. (Boraginaceae) collected from Kashmir Himalaya, India, is cytologically analyzed for the first time revealing 2n=2x=24 (diploid).

Production of Triploid Germplasm by Inducing 2n Pollen in Longan

open access: yesHorticulturae, 2022
Longan (Dimocarpus longan Lour.) is of great economic significance in South China for its unique taste and nutritional properties. However, longan breeding is mainly based on seedling selection, which generally results in small fruits, low flesh recovery,
