Mace varieties

ICAR-Indian Institute of Spices Research (IISR), Kozhikode, Kerala · ICAR-IISR · 2001

High myristicin and elemicin content in both nut and mace oils; low fruit rot incidence from Diplodia species. Significantly outperforms earlier varieties in aromatic chemical composition with stronger spicy profile.

ICAR-Indian Institute of Spices Research (IISR), Kozhikode, Kerala; selected from Burliar, Nilgiris, Tamil Nadu germplasm · ICAR-IISR (farmer participatory breeding) · 2013

First nutmeg variety developed through farmers' participatory breeding. Mace and nut oils rich in sabinene and myrcene (for delicate aroma) with intentionally low myristicin and elemicin. Bold nut, thick and entire mace that fully covers seed.

Dr. Balasaheb Sawant Konkan Krishi Vidya Peet (DBSKKV), Fruit Research Station, Vengurla, Maharashtra · Dr. Balasaheb Sawant Konkan Krishi Vidya Peet (SAU) · 1998

Only hermaphrodite nutmeg variety released in India. Both male and female flowers on same tree, eliminating the major plantation problem of 50% unproductive male trees; each tree can produce fruit. Suited to Konkan's humid, warm coastal climate.

High-yielding variety with bold nuts and notably thick mace. Major contribution to Konkan's spice economy.

Idukki district, Kerala (developed in wild forests from original seed from Kottayam) · Varkey Thomman (farmer-developer, 1994); continued and recognized by Shajan Varghese (son) · 1994 (formal development); 2015 recognition by National Innovation Foundation; 2024 Best Spice Farmer (Innovation) Award from IISR

Extra-large nut variety—4.5 cm long × 3 cm wide, far exceeding standard sizes. High annual productivity (3000 fruits per mature tree). Organically cultivated, low-maintenance, pest-tolerant. Farmer-led improvement model widely recognized nationally.

Vaikaprayar near Vakim, Kottayam district, Kerala · Joseph (farmer from FACT background); recognized and registered by Kerala Agricultural University (KAU) · 2018 (official KAU recognition and registration); Plant Genome Saviour Award (year not specified in available literature)

Produces unusually large, consistent nutmegs in huge bunches from single trees. Dried nutmeg weighs minimum 10g, selected specimens 16g. KAU recognition indicates official merit. Recipient of multiple awards including Sugandhsree Innovative Farmer Award (2019) and Best Spice Farmer (Innovation) Award from IISR (2024).

Native to Kerala and south-western India (Malabar region historically); also wild/semi-cultivated in Nilgiris, Kottayam, Idukki · Farmer selection over centuries; not formally bred · Pre-colonial (17th century trade history); modern cultivations trace to 1800s–present

Darker, more flavorful nutmeg than West Indian types; higher myristicin concentration (5-13%). Premium in global spice markets. Multiple local landraces within Malabar type distinguished by size and aromatic profile.

Across Kerala nutmeg-growing regions (Thrissur, Ernakulam, Kottayam); identified via Participatory Varietal Selection (PVS) surveys · Farmer-maintained landraces; identified and characterized by Kerala Agricultural University (KAU) · Surveyed 2010–2014; five varieties released as KAU-farmer varieties (exact years not specified in available literature)

PVS approach identified five superior clones from 29 mother trees based on economic yield traits (nut size, mace thickness, fruit number). Diversity reflects century-long farmer selection across Kerala's varied microclimates.

South-western India (native range); Konkan coast and Western Ghats · Not formally bred; wild and semi-cultivated populations · Ancient/pre-colonial; not formally released

Alternative nutmeg species producing lower-grade, milder spice with minimal aroma. Lacks fragrance characteristic of true nutmeg. Historically used as adulterant in true nutmeg trade. Not commercially significant for spice production in India.

Occurs sporadically (estimated 5% frequency) in mixed seedling populations; Konkan Sugandha is the only formally released hermaphrodite variety · Natural occurrence; selected and released via DBSKKV (Konkan Sugandha) · Konkan Sugandha formally released 1998

Bears both male and female flowers on same tree, solving the 50% male tree problem of dioecious breeding. Reduces plantation inefficiency. Konkan Sugandha is the sole released example.
