Genetic Analysis of Yield Components and Fiber Strength in Upland Cotton (Gossypium hirsutum L.)
Huseyin Basal and Ismail Turgut

Abstract: In this study six different cotton genotypes, Nazilli-84, Acala SJ-5, Deltapine 5690, Carmen, Tamcot CAMD-E and PD 6186, were crossed in a half diallel mating scheme. The result of diallel analysis indicated that, the number of Bolls per Plant (B/P), Seed Cotton Weight per Plant (SCW/P), Lint Percentage (LP) and Earliness Ratio (ER) exhibited additive and dominance genetic effect but primarily dominance genetic effect, that fiber Strength (Str.) had about equal additive and dominance genetic effect and that seed cotton Weight per Boll (BW) exhibited primarily additive genetic effect. The highest heritability estimates were found in earliness ratio (0.53), fiber strength (0.50), seed cotton weight per boll (0.42) and lint percentage (0.40). The number of bolls per plant and seed cotton weight per plant showed moderate heritability estimates, 0.33 and 0.22, respectively. Results suggest some suitable parents which are; Nazilli 84 and Carmen for plant seed cotton yield and lint percentage; Acala SJ-5 for boll weight; DPL 5690 for number of bolls per plant; Tamcot CAMD-E for earliness ratio; PD 6168 for fiber strength. These varieties mentioned above could be suitable parents in cotton breeding program for further researches.
