  To study inheritance of CLCuV, nine selected varieties/lines (four resistant five susceptible) of up land cotton (G. hirsutum L.) were used for five F1 combinations. The F1 was sown for raising F2 and back crossing purpose. Subsequently P1, P2 F1, F2, BC1 and BC2 population were established and to ensure the inoculation of CLCuV no pesticide was used to control insect population. The results indicated that duplicate dominant epistasis was involved in control of resistance of CLCuV. Virus resistance was controlled by two dominant duplicate genes as F2 ratio was modified to 15:I from 9:4:4:1 and the test cross ratio was modified to 3:1 instead of 1:1.

  The node above white flower (NAWF) technique was used to monitor the growth, development and maturity of ten cotton varieties viz. Reshmi, CIM-443, MNH-93, MNH-329, MNH-395, MNH-439, S-12, FH-900, CIM-1100 and NIAB-78 during the years 1997, 1998 and 1999. The NAWF counts were made at weekly intervals. By regressing NAWF means over time, the number of days to reach NAWF of 5.0 (NAWF-5) was determined. Days to NAWF-5 were highly correlated with percent first pick of seed cotton yield. It was observed that NIAB-78 and CIM-443 achieved NAWF-5 earlier by 109.86 and 109.09 days (average of three years). Days to NAWF-5 provided a focal point for all management decisions. Therefore, it became evident that NAWF technique could be used for monitoring cotton plant after flowering, earliness determination of variety/strain and detecting fruiting problems during growth season.
