CAULIFLOWER

Varieties have been divided into four different maturity groups (I-IV) for northern Indian plains:

Maturity group	Nursery sowing time	Transplanting time	Opt. temp. range for curding	Varieties
Extra Early: May maturity (May-June)	End of February	March	24oC-30oC	Pusa Meghna, DC 23, Pusa Kartik Sankar
Early I (A) Sept. maturity (mid Sept.-mid Nov.)	Mid May	July beginning	20-25oC	Early Kunwari, Pusa Early Synthetic, Pant Gobhi-3, Pusa Meghna, Pusa Kartik Sankar
I (B) Oct. maturity (Mid Oct.-mid Nov.)	May end to Mid June	Mid July	20-25oC	Pusa Katki, Pusa Deepali, Pant Gobhi-2
Mid Early (II) Nov. maturity (Mid Nov.-mid Dec.)	July end	Sept. beginning	16-20oC	Improved Japanese, 12-C, Pusa hybrid-2, Pusa Sharad, Pant Gobhi-4
Mid late (III) Dec. maturity (mid Dec.-mid Jan.)	Aug. end	Sept. end	12-16oC	Pusa Synthetic, Pusa Subhra, Palam Uphar, KT-25, Pant Subhra, Pusa Him Jyoti, Pb. Giant 35, Pusa Paushja, Pusa Shukti
Late (IV) Snowball (Jan.-March)	Sept. end to mid Oct.	Oct. end-mid Nov.	10-16oC	Snowball 16, Pusa Snowball-I, Pusa Snowball K-1, Dania, Ooty-1

Cauliflower cultivars grown in India can be classified in two broad groups:

1. Indian Cauliflower/tropical/hot weather/heat tolerant.
2. European types/early temperate type also known as Snowball or late cauliflower

Indian Type	European Type
Tolerant to heat	Not tolerant to heat
Curd formation at and above 20oC	Curd formation at 5-20oC
Yellow to creamish curds, loose with strong flavour	Snow white curds with very mild or no flavour (better quality curds)
Plants are short having long stalk and loosely arranged leaves	Steady plants and long leaves giving protective jacket to curd
Early in maturity	Late in maturity
More variable (heterozygous)	Less variable (homozygous)
More self-incompatible	Less self incompatible
Small juvenile phase	Long juvenile phase
No need of vernalization but needs cold treatment at 10-13oC	Needs vernalization at 7oC for 8-10 weeks
