Yielding Ability and Stability Analysis of Hunan Province Self-fertile Flue-cured Tobacco Strains in Regional Trail
This paper took 10 strains of Hunan province self-fertile flue-cured tobacco as materials for regional tests, and analyzed the productivity and stability of the test results. It showed that, in the four tobacco-producing district of Hu-nan Province, the output value of strain V10 ( 0522 ) was highest, reached 42918.57 yuan/hm2;strains ( species) and site interaction variance and variance value was minimum, and the regression coefficient was less than 1. It had good sta-bility and adaptability besides high yield. The output value and stability of V8 (CZ-24) were higher than the control V11 ( K326 ) , so V8 is worthy popularizing in some extend. Strain V2 ( C72-6-2 ) , V7 ( 0511 ) were also higher than the control V11 (K326) in output, with value of 39 941.37 yuan/hm2 and 37 536.23 yuan/hm2, respectively. But their stability was not ideal. The remaining was inferior to the control V11 both in yield and stability.
