Among the different zones where FCV tobacco is grown in India, Northern light soils of Andhra Pradesh, where the crop is grown in light sandy soils under irrigation and Karnataka light soils, where the crop is grown under monsoon conditions, are important zones producing semi-flavourful and good quality neutral filler tobacco. The style of tobacco produced in these two zones are lemon to orange coloured, open grained and medium bodied with chemical and physical qualities in acceptable range. In recent years, two varieties (exotic introductions) viz. NLS 4 (K326) and NLS-5 (K394) have been grown in Northern light soils of Andhra Pradesh. These varieties yielded 1800 to 2200 kg ha-1. NLS-4 is resistant to black shank and tolerant to root-knot nematode while NLS-5 is susceptible to these diseases. Both the varieties require 70 to 80 kg N ha-1 to produce maximum yield of good quality tobacco. These two varieties were accepted by the trade and farmers in general. Large scale trials in Karnataka identified two varieties viz. NLS 4 (K326) and FCH-6534. Under monsoon conditions of KLS, NLS-4 yielded 1900 to 2100 kg ha-1 and FCH-6534 has yielded 1700 to 2000 kg ha-1. Both the varieties are resistant to black shank disease and tolerant to root-knot nematode. Cured leaf of these varieties are deep lemon to orange coloured, open grained, medium to thin bodies, fluffy, nicotine varying from 1.6 to 2.3%, reducing sugars 18 to 22%.
