Abstract
SVPR 4 is a high yielding superior medium staple cotton variety developed at Cotton Research
Station, Srivilliputtur. It was released in the year of 2009 for summer irrigated/ Rice fallow
cotton tracts of Tamil Nadu. It is a hybrid derivative of the cross between MCU 5 and S 4727.
SVPR 4 cotton is robust in nature with determinant growth habit and matures in 150 days. It
has recorded an average seed cotton yield of 1583 kg/ha which is 13.0 % increase over SVPR
2. Its fibre qualities are comparably superior to SVPR 2 with 27.9 mm span length and 22.5 g/
tex strength. The cotton SVPR 4 can spin 40’s counts which is the current demand of the
textile Industries. It is moderately resistant to leaf hopper and tolerant to drought in summer
irrigated season. Hence, SVPR 4 cotton was released as an alternate variety to replace SVPR
2 in summer irrigated cotton area and SVPR 3 in rice fallow tracts of Tamil Nadu.
