Senior Scientist
Areas of Interest: 

My primary research interests are (I) Development of high yielding varieties, and promising parental/CMS lines having better combining ability & heterotic hybrids; (II) Identification of stress tolerance genotypes (heat, humid, black rot, etc); (III) Tropicalization of typically temperate vegetables; (IV) Development of robust CMS lines to facilitate hybrid breeding & ecomonize seed production of F1 hybrids; and (V) Improvement in nutrient/vitamins/colour/antioxidants/anthocyanins/pigment/bioactive content in genotypes/varieties/hybrids of cole crops (Cauliflower, Cabbage, Kale), root vegetables (Radish, Carrot) and leafy greens (Leafy chenopod, Beet leaf).

(3) Developed varieties/promising lines of red/orange/black/yellow carrots [Kashi Arun (Red root); Kashi Krishna (Black root)].

(4) Developed varieties/promising lines of leafy chenopod i.e. Bathua [Kashi Bathua-2 (Green leaf); Kashi Bathua-4 (Purplish-green leaf)].

(5) Developed varieties of Basella i.e. Poi [Kashi Poi-1 (Procumbent growth habit, Cordate leaf shape); Kashi Poi-2 (Bushy, Ovate leaf shape); Kashi Poi-3 (Twining growth habit, Purple coloured petiole and stem)].

(6) Developed varieties/promising lines of purple/green-podded vegetable French bean (Snap bean) [Kashi Rajhans (Thin pod, White seed); Kashi Baingani (Purple pod, pole type); IC 0611107 (Mizoram state); Kashi Agrim (Early, Autumn sowing, Short duration)].

(7) Tropicalization of temperate vegetables: Tropical kale (VRKALE-1, VRKALE-9); Tropical cabbage (VRCAB-111); Tropical orange carrot (VRCAR-141). 

Patents, Technology, Methodology, Genetic Stock, Variety, etc.:: 

VRRAD-201 (INGR20032, Radish): First Ogura-CMS line from Public Sector in India; Robust CMS system with better combining ability and heterosis; and Sinuate type of leaf shape i.e. leaf morphology (leaf division incision).

Kashi Kale-1 (INGR20035, VRKALE-1, Kale): A unique tropical kale- First of its kind in the world developed at ICAR-IIVR, Varanasi, UP; It doesn’t require vernalization; and bolts, flowers and sets seeds in spring season of Varanasi, UP having 11-24 °C temperature, 54-91% RH and 5.5 h day light during January-February i.e. 60 days before flowering.

Kashi Gobhi-25 (Cauliflower): Develops curds at 22-27 °C temperature i.e. first fortnight of November in Indo-Gangetic plain of North Indian (Katki maturity); and suitable for transplanting during 4th week of July to 2nd week of August. Curds are hemispherical in shape, whitish in colour and compact.

Kashi Arun (Carrot): Roots are attractive red in colour, self-coloured core, 21-23 cm in length, 110-125 g in weight, 8.5-9.0 °B TSS and Danvers (triangular) in shape. Ready to harvest in 85-95 days and produces marketable root yield of 300-350 q/ha.

Kashi Krishna (Black Carrot): Roots are black (solid purple) in colour, Danvers (triangular) in shape, ready to harvest in 95-105 DAS, self-coloured core, high yielding (200-250 q/ha), and richest source of anthocyanins (275-300 mg/ 100 g) and antioxidants. Suitable for salad, juice, halwa, nutraceutical and food supplement purposes.

Kashi Lohit (Red Radish): Attractive red coloured roots, 22-23 cm in length, ready to harvest in 40-42 DAS, yield potential of 40-50 t/ha, high in anthocyanins (4 mg/100g FW), good source of vitamin-C and higher antioxidant activity.

Kashi Mooli-40 (Radish): Develops root at 15-40 °C temperature, higher root yield (22-27 t/ha) during mid-April to mid-May harvesting, roots are ready to harvest in 45-50 days after sowing, tolerant to pithiness and delayed bolting.

Kashi Aardra (Radish): Attractive dark-green and soft leaves with entire leaf-margin, roots are retentive white, long and icicle in shape, and marketable yield is 45-50 t/ha.

Kashi Bathua-2 (Leafy chenopod or Bathua): Luxuriant plant growth, green coloured leaves, excellent source of vitamin C, vitamin A, folic acid, minerals, phenolics and antioxidants. Attains plant height of 1.8-2.0 m and produces biomass yield of 35-38 t/ha.

Kashi Bathua-4 (Leafy chenopod or Bathua): Luxuriant plant growth, purplish-green coloured leaves, good source of vitamin C, vitamin A, folic acid, minerals, phenolics and antioxidants. Attains plant height of 2.00-2.25 m and produces biomass yield of 40-42 t/ha.

Kashi Rajhans (French bean): Bushy in nature, better pod quality (thin, round, slightly curved, slower seed development, fleshy, free from parchment and smooth surface), and seed is white in colour.

Kashi Baingani (French bean): Pole in nature, purple coloured pod, better pod quality (round, slightly curved, fleshy, free from parchment and smooth surface), rich in anthocyanins (7.0-7.25 mg/100 g FW) & antioxidants, and seed is light brown in colour.
