Somaclonal variation for genetic improvement in grasspea (Lathyrus sativus L.)
Open accessAbstract
Somaclonal variation was revealed among regenerants in four genotypes (Nirmal, P24, Nayagarh local and Dhenkanal local) of grasspea (Lathyrus sativus L.) following long term in vitro culture of internode explants. Most of the somaclones which survived till maturity had revealed chromosomal abnormalities and variation in one or more morphological and/or agronomic traits. Some of the variant phenotypes especially those relating to developmental variations were not inherited to R2 generation owing to elimination of chromosomal aberrations that preclude normal morphogenesis. Somaclones with variation in flower colour, seed colour, leaflet length and breadth, foliage and pod pigmentation may be used as genetic markers in breeding Lathyrus sativus. Besides, variants with broad leaf, dwarf height, long pod, large seed, short duration and synchronous maturity are agronomically desirable. A large seeded somaclone NGOG 5 having high seed yield and low neurotoxin content (ODAP) recovered in this pursuit, can be a desirable candidate for future breeding programme.

In Lathyrus sativus, 26% of regenerants derived from long-term callus cultures frequently presented chromosomal abnormalities including precocious and/or late separations of bivalents, anaphase laggards, anaphase bridges, chromosome rings, and other rearrangements.
“A similar situation was noticed for Lathyrus sativus L., a medicinal plant used in the homeopathic treatment of spinal cord affections, 26% of the regenerants derived from long-term callus cultures frequently presented precocious and/or late separations of bivalents, anaphase laggards, anaphase bridges with or without acentric fragments, chromosome rings, and other common chromosomal rearrang”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
