Cotton SVPR 6 (TSH 04/115) – A high yielding long staple cotton variety for southern zone of India and winter/summer irrigated tracts of Tamil Nadu
Abstract
A high yielding long staple hirsutum cotton variety SVPR 6 (TSH 04/115) was developed by Cotton Research Station, Srivilliputtur and released in the year of 2017. It was notified during the year 2018 for kharif season for the southern zone of India under winter irrigated and summer irrigated tracts of Tamil Nadu. It is a hybrid derivative of the cross between SVPR 2 and BJA 592. SVPR 6 cotton is semi spreading in nature with determinant growth habit and matures in 155 days. It has recorded its potential yield of 3392 kg/ha at Raichur during 2013-14. The overall performance revealed that the cotton culture TSH 04/115 was superior over Suraj and SVPR 4 with an average seed cotton yield of 2285 kg/ha which is 11.5 % and 30.9 % increase over the zonal check Suraj (2049 kg/ha) and local check SVPR 4 (1589 kg/ha) respectively . This culture comes under the long staple category with an average upper mean half length of 29.5 mm, fibre strength of 27.3 g/tex and micronaire value of 4.0. It can spin upto 40’s counts. It is moderately resistant to jassid and white fly besides tolerance to Bacterial leaf blight and Alternarialeaf spot.
