Plantago ovata plant named ‘Mayuri’

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.

1. A distinct high yielding, early maturing Psyllium ( Plantago ovata  F.) variety plant ‘Mayuri’ as described and illustrated with developmentally expressed pigment marker and possessing the following characters:
 (a) Yellow green group (145A) upper surface, Yellow green group (145B) lower surface of the leaf,  
 (b) inflorescence having green group (143C) florets which turn Gray purple group (184D) on maturity,  
 (c) randomly amplified polymorphic DNA (RAPD) profile for polymerised chain reaction (PCR) amplified DNA segment using 14 primers distinct from the other existing varieties,  
 (d) high seed yield (11 to 12 q/ha) and high seed husk yield (2.3 to 3 kg/ha) compared to other check (control variety),  
 (e) early maturity (100-110) in comparison to other genotypes,  
 (f) development of pigment in the panicle showing stage of colour from green to gray purple as a detectable marker indicating the maturity time for harvesting to avoiding seed shattering, and  
 (g) swelling index is 443.80 in comparison to other varieties.
