用一个参数和两个参数的2种直线回归分析方法,分别时5个番茄一代杂种的红 熟果实,在不同采收期进行番茄红素含量遗传稳定性分析和比较。两种分析方法的 结论基本一致。而两个参数的直线回归分析把“遗传型与环境互作效应”分解成各 遗传型的适应性,及适应性的稳定性,显得比较正确,‘浙园6-73’(V3)遗 传型具有高茄红素含量,对环境敏感,且敏感性稳定(α=0.623,λ=0.223; b>1).杭州6月平均气温24℃,Vs的番茄红素含量为9-10毫克/100克以上,7月中下旬平均气温升高至29℃,番茄红素下降到4毫克/100克左右。对此,宜选择和创 造优良的环境条件,可期望获得高含量的番茄红素。‘红丰’(V5)的番茄红素含量 中等水平,是趋向完全稳定的类型(α=0.513,λ=2.767;b<1)。在特定条件 下,不同遗传型的番茄红素含量相对表现不同,构成不同加工时期的品种组群.应 选育番茄红素含量高的稳定型或平均稳定型的加工专用品种。
Two kinds of linear regression analysis methods of one parameter and two parameters were used to analyze and compare the genetic stability of lycopene content of five tomato hybrids at different harvest time. The conclusions of the two analysis methods are basically the same. Linear regression analysis of the two parameters decomposes the interaction effect between genotype and environment into the adaptability of each genotype and the stability of adaptability, which is more correct. The genotype of Zheyuan 6-73 ’(V3) With lycopene content, sensitive to the environment and stable (α = 0.623, λ = 0.223; b> 1). The average temperature of Hangzhou in June was 24 ℃. The Lycopene content of Vs was 9-10 mg / 100g. The average temperature rose to 29 ℃ in mid-July and the lycopene dropped to 4 mg / 100g. In this regard, should choose and create excellent environmental conditions, can expect high levels of lycopene. The average lycopene content of ’Hongfeng’ (V5) was a trend toward complete stability (α = 0.513, λ = 2.767; b <1). Under certain conditions, the lycopene content of different genotypes showed relatively different performance and constituted different breed groups at different processing stages. Breeding should be high-lycopene stable or average stable special varieties for processing.
