Benefits of technology

The invention is a new variety of psyllium (a type of plant) that matures early and produces a distinct pigment marker to indicate maturity. This variety has high yields of seeds and husks, and is resistant to shattering (when seeds are broken open during harvest). The variety can be propagated both by seed and asexually, and can be commercialized for use.

Problems solved by technology

Owning to limited genetic variability, genetic diversity and the improved varieties for commercial cultivation, the production is not as much as expected.

Embodiment Construction

[0011]Under genetic improvement programme of isabgol, mutation breeding (Gamma rays irradiation: 10-100 kR doses) was initiated in an inbred line developed from ‘CIMAP / L1’ (three generation selfed) to induce variability in its genetic background and select for desirable polygenic mutants (early maturity with indicator / marker for colour at the time of the maturity, high seed and husk yield) suitable for commercial cultivation. Eight promising mutants were selected from different treatments in M2 and evaluated in Initial Evaluation Trial for three consecutive years (1997-1999, M4-M6). These mutants were also evaluated in Bench Scale Trial for three consecutive years (1998-1999), and the most promising mutant CIMAP / S 5 at 20 kR dose was also evaluated further in Pilot Scale Trial for two years (1999-2000).

[0012]This work was conducted at main center, Lucknow, Uttar Pradesh, India. On an average, the elite strain CIMAP / S 5 registered its superiority over the control variety Niharika (no...

Abstract

This invention relates to a new distinct early maturing, high seed and husk yielding variety of psyllium (Plantago ovata) designated as var. ‘Mayuri’ with the distinct pigment marker of the panicles relatable to the maturity thereby indicating the right harvesting stage to prevent the seed shattering, a problem in psyllium. This variety was developed by mutation breeding (gamma rays irradiation) and propagated by seeds for commercial cultivation. The new variety could be differentiated from the other variety through unique RAPD profile and has been tested for uniformity and stability of characters defined. Psyllium plant ‘Mayuri’ with stage marker and early maturity.

Description

FIELD OF INVENTION[0001]Genus and species: Plantago ovata. [0002]Variety denomination: Mayuri.[0003]The present invention relates to a new distinct early maturing, high seed and husk yielding variety of the genus Plantago, species ovata, (common name “psyllium”) designated as the variety ‘Mayuri’.[0004]This invention further relates to the distinct pigment indicator marker of the panicles relatable to the maturity, serving as signal for harvesting stage. The new distinct plant variety of psyllium has been developed by mutation breeding (gamma rays irradiation). The variety can be propagated asexually, but can conveniently be propagated by seed for commercial cultivation.BACKGROUND OF THE INVENTION[0005]Psyllium (Plantago ovata), family—Plantaginaceae a plant of west Asian origin was introduced into India the middle age. It is important for its seeds and husk in traditional system of medicine. India continues to hold a monopoly in its production and trade in the world market. Thus, i...
