Abstract


ine two entries of cotton viz., JK 260 and Sharada were studied for biochemical and physical components to identify the bases of resistance. The balls of JK 260 had high rind thickness compared to the bolts of Sharada, in all ages of observation; Total phenols decreased with an increase in boll ade in both entries which varied from 0.98 mg/g to 042 mg/g in JK 260 and from 0.80 mg/g to 0 31 mg/g in Sharada. Total sugars and nitrogen content decreased with increasing age in both entries. The crude fibre content was 29,40 and 25 60 per cent in JK 269 and Sharada respectively when the bolls were 40 Jays 'old.
