湖南省自育烤烟品系区域试验丰产性及稳定性分析

摘要

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.%以湖南省10份自育烤烟品系为材料进行区域试验,并对试验结果进行丰产性及稳定性分析。结果表明,在湖南省4个烟区,品系V10(0522)产值最高,达到了42918.57元/hm2,品系(种)与地点互作方差和变异度值最小,且回归系数小于1,高产的同时稳定性也好,适应性强；品系 V8(CZ-24)的产值和稳定性均高于对照 V11(K326),有推广利用的价值；品系V2(C72-6-2)、V7(0511)的产值均高于对照V11(K326),其产值分别为39941.37元/hm2、37536.23元/hm2,但其稳定性表现均不理想；其余品系丰产性及稳定性均不如对照V11(K326)。
