Abstract:
... Challenges for wheat doubled haploid (DH) production using anther culture include genotype variability in green plant regeneration and spontaneous chromosome doubling. The frequency of chromosome doubling in our program can vary from 14% to 80%. Caffeine or trifluralin was applied at the start of the induction phase to improve early genome doubling. Caffeine treatment at 0.5 mM for 24 h significan ...

Abstract:
... A new species of Salacia is described from Karnataka and Kerala states of the Western Ghats, India. It is unique within the genus on account of its obliquely dehiscing anthers and 7–10 cm long, prolate to broadly ellipsoid or ovoid, keeled, greenish‐yellow 5‐ to 8‐seeded fruit with thin epicarp and dry mesocarp. Salacia megacarpa sp. nov. can be grouped with S. fruticosa Heyne ex M.A.Lawson and S. ...

Abstract:
... Plant anther culture allows for the regeneration of uniform and homozygous double haploids. However, off-type regenerants may appear as a result of so-called tissue culture-induced variation (TCIV). In addition, the presence of Cu²⁺ and Ag⁺ ions in the culture medium might influence the number of green plants. The regenerants were obtained via anther cultures of barley under varying Cu²⁺ and Ag⁺ i ...

Abstract:
... One of the limitations in obtaining the genetic diversity of doubled haploid (DH) lines via anther culture is the development of families of regenerants, and each family represents a clone. This work examines the results of studying this phenomenon in anther culture of alloplasmic (H. vulgare)–T. aestivum and euplasmic lines with 1RS.1BL and 7DL-7Ai translocations and hybrids between them.

Abstract:
... Creating tetraploid rice is a promising field in increasing crop yields. There are currently no commercial rice varieties due to poor panicle grazing, which is caused by low pollen fertility. It is stated in the scientific literature that tetraploid plants are obtained in vitro androgenesis as an additional starting material. The aim of the study was to study the characteristics of callus in anthe ...

Abstract:
... An immense increase in human population along with diminished lands necessitates the increase of rice production since, it serves the human population as a staple food. Though rice hybrids (RH) are showing considerable yield enhancement over inbreds in terms of both quality and quantity, farmers’ adoption of hybrid rice technology has been much slower than expected because of several constraints s ...

Abstract:
... The taxonomic limits of Styphelia (Ericaceae, Epacridoideae, Styphelieae) have been contentious since the genus was first described. At one extreme, it has been circumscribed so broadly as to include most epacrids with drupaceous fruit, at the other, to include only those species that also have long-exserted anthers and styles. Recent molecular phylogenetic analyses have indicated that while all p ...

Abstract:
... The assembly of superior varieties and collection of rice germplasm involves the process of selecting and storing elders that have superior genotypic properties and phenotypes.

Both lateral and vertical herkogamy showed continuous variat ...

With several recently described species in the last decade, the knowledge on Bertolonia’s distribut ...
