(Seed Health Management for Better Productivity)• Standardized cultivation of Calocybe indica using wheatstraw as a substrate with casing of FYM + Spent Compost+ Sand (2:1:1).• A relay cropping schedule developed for Tarai region ofUttaranchal: two crops Agaricus bisporus (Sept. - March), fourcrops Pleurotus spp. (Sept.- Nov. and Feb.,- April) and threecrops of Calocybe indica (March-October).Calocybe indica• Developed two strains of Agaricus bisporus, Pant 31 and Pant 52, now included in multilocationaltesting under coordinated trials.• Development and commercialization of seven hybrids of oyster mushroom.• Associated with multilocational testing and release of the strains NCS-100, NCS-102, NCH-102 ofA. bisporus.• 120 mushroom species from different locations in Uttaranchalhave been collected and preserved in the museum of thecentre.• Of the collected mushrooms five Auricularia, four species ofPleurotus and two species of Ganoderma have been broughtunder cultivation.• Developed / standardized technology for production of traditional Ganoderma lucidumvalue added mushroom products viz. ‘Sev’, ‘Warian’, ‘Papad’ and ‘Mathri’.• Isolated a high value cater pillar mushroomCordyceps sinensis from high altitudes ofUttaranchal and analysed for antioxidativeproperties.Cordyceps sinensisMAJOR ACHIEVEMENTS‣ Twenty seven wheat lines, combining better agronomic characteristics and resistance to diseasesincluding Karnal bunt have been identified (Shanghi-4, BW 1052, HUW 318, Lira/Hyan’S’ VUI’S’,CUMPAS 88, BOBWHITE, SPRW 15/BB/Sn 64/KLRE/3/CHA/4/GB(K)/16/VEE/ GOV/AZ/MU, NI9947,Raj 3666, UP 1170, HS 265, HD 2590, HS317, PH 130, PH 131, PH 147, PH 148, PH 168, HW 2004,GW 188, MACS 2496, CPAN 3004, K8804, K8806, ISWYN-29 (Veery”S”) and Annapurna).‣ Foliar blight of wheat has now been assumed as a problem inTarai areas of U.P and foothills of Uttaranchal. Bipolarissorokiniana - Dreschlera sorokiniana, was found associatedwith the disease in this area. Karnal bunt of wheat caused byTilletia indica Mitra, is widely distributed in various Westernand Eastern districts of U.P while the North hills and Southerndry areas are free from the disease.- 16 -
(Seed Health Management for Better Productivity)‣ Multiple disease control in wheat has been obtained by seed treatment with Raxil 2DS @1.5g/Kg seed + one foliar spray fungicide Folicur 250 EW (Tebuconazole) @ 500ml/ha, whichcontrols loose smut, brown rust, yellow rust, powdery mildew and leaf blight disease veryeffectively.‣ The mixture of HD 2329 + WH 542 + UP 2338 produced highest yield recording 11.67 per centhigher as compared to average yield of their components.‣ Among new fungicides Raxil 2DS (Tebuconazole) @ 1.0, 1.5, 2.0 and 2.5g/kg seed, Flutriafoland Dividend @ 2.5g/Kg seed were found highly effective in controlling the disease. Raxil 2DS@ 1.5g/Kg seed as slurry treatment gave complete control of loose smut.‣ New techniques for embryo count and seedling count for loose smut, modified partial vacuuminoculation method of loose smut, creation of artificial epiphytotics of Karnal bunt, NaOH seedsoaked method for Karnal bunt detection and detached leaf technique for screening againstleaf blight using pathogen toxin developed.‣ The major emphasis has been on the screening of maize germplasms to various diseases withspecial reference to brown stripe downy mildew, banded leaf and sheath blight and Erwiniastalk rot. A sick-plot has been developed to ensure natural source of inoculum. Efficienttechniques for mass multiplication of inoculum and screening of germplasms have beendeveloped to create epiphytotic conditions. The selected genotypes have been utilized forevolving agronomically adaptable varieties. Several promising hybrids and composites havedeveloped and released following interdisciplinary approach.‣ Studies on estimation of yield losses, epidemiological parameters on various economicallyimportant diseases of maize have been worked out to evolve suitable control measures andhave been recommended to farmers in the region.‣ Based on the survey and surveillance studies the information on the occurrence of variousdiseases in UP and Uttaranchal, a disease map has been prepared and monitored to finalize theout breaks of one or more diseases in a given area based on weather parameters. It will help thegrowers to be prepared to save the crop from recommended plant protection measures.‣ An repository of >600 isolates of biocontrol agents developed at Pantnagar & Ranichauri.These isolates are suited for different crops & agro-ecological conditions.‣ Standard methods developed for testing hyphal and sclerotial colonization.‣ Isolate of T. virens capable of colonizing sclerotia of Rhizoctonia, Sclerotium and Sclerotiniaisolated for the first time. It may have great potential.‣ 16 new technologies related with mass multiplication and formulation of microbial bio-agentsdeveloped and are in the process of being patented.‣ Several genotypes including SPV 462, SPV 475, SPV 1685, SPH 1375, SPH 1420, CSV 13,CSV 15, CSH 14, CSH 16, CSH 18, G-01-03, G-09-03, GMRP 91, RS 629, UTFS 45, UTMC523 and AKR 150 have been identified with high level of resistance to anthracnose and zonateleaf spot diseases.- 17 -
