  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 present study was conducted on correlation and path coefficient analysis of earliness an agronomic characters of upland cotton. The results showed that node of first fruiting branch, number of monopodial and sympodial branches plant-1, number of flowers and number of bolls per plant-1, boll weight, fiber fineness (micronaire) value and fiber strength were positively and significantly correlated with yield in present material. Similarly path coefficient analysis revealed that number of sympodial branches and number of flowers plant-1, number of bolls plant-1 and boll weight had maximum direct positive effect on yield of seed cotton. Whereas, the traits number of monopodial branches plant-1, ginning out turn percentage (GOT%) and staple length had the direct negative effects on seed cotton yield plant-1. The results indicated that for evolving a superior genotype possessing all the three basic characteristics i.e. earliness, high yield and improved fiber quality of international standard, the breeder had to use the reciprocal recurrent selection method or modified back cross or three way cross within genetic material under study.
