PMH1-LP(low phytic)

Parent: LM 13-LP3 × LM 14-LP4
Year of release: 2022
Gazette Notification: S.O. 4065(E). S.N. 70
Season: Kharif
Yield: 9.0 to 10.0 t/ha
Maturity: Long (95-100days)
Recommended for cultivation in: North Western Plains Zone (NWPZ) comprising the states of Punjab, Haryana, Uttar Pradesh (Western region), Uttarakhand (Plains) and Delhi.
Special features:      PMH1-LP, an improved version of PMH 1 for one of the major anti-nutritional factor phytic acid (PA). The PA content in the PMH1-LP is 1.89 mg/g of endosperm, whereas in the original hybrid PMH 1 it was 2.94 mg/g. The PA content in PMH1-LP was reduced by 36%. The inorganic phosphate (Pi) content in PMH1-LP is 0.66 mg/g and in original hybrid PMH 1, it was 0.26 mg/g. The Pi content was increased by 140% in the improved version (PMH1-LP) as compared to original hybrid, PMH 1. PMH1-LP showed moderate resistance (MR) to major diseases of north western plains zone (NWPZ) namely maydis leaf blight (MLB) and charcoal rot (ChR) It also showed similar resistance (R) reaction as that of original hybrid PMH 1 to ear damage by fall armyworm, Spodoptera frugiperda (J.E. Smith) and moderately resistance (MR) to leaf injury by Chilo partellus (Swinhoe) and fall armyworm, Spodoptera frugiperda (J.E. Smith) with the disease score of 2.6, 5.7, and 4.4, respectively
