摘要

在印度泰米尔纳德邦奇丹巴拉姆的Shivapuri进行了一项估计遗传变异参数的实验。通过对46个茄子基因型的遗传调查，估计了遗传变异参数，即表型(PCV)和基因型(GCV)变异系数、范围、平均值、遗传进阶和遗传力。由基因型引起的方差分析显著，表明所研究的基因型多种多样。各性状的PCV均略高于GCV，表明环境影响较小。单株产量和产量相关性状(如果重、果长、单株果数和每簇果数)的遗传力和GAM值较高，表明这些基因型在茄子产量改良中具有包容性。此外，还可以研究这些基因型的遗传配合力和特异性配合力，以便将有价值的地方品种纳入特定地点和特定目标的育种计划中。

Genetic Investigation of Yield and Related Components in Some Landraces of Brinjal (Solanum melongena L.)

An experiment was conducted at Shivapuri, Chidambaram, Tamil Nadu, India for estimation of genetic variability parameters. The genetic investigation studies in 46 brinjal genotypes estimated genetic variability parameters namely Phenotypic (PCV) and Genotypic (GCV) coefficient of variation, range, mean, genetic advance and heritability. The ANOVA due to genotypes is found to be significant indicating the genotypes under study are diverse. The PCV for all characters were slightly higher than GCV, indicating the presence of little environmental influence. The high values of heritability and GAM for yield per plant and yield related traits like fruit weight, fruit length, number of fruits per plant and number of fruits per cluster suggest the inclusivity of these genotypes for yield improvement in brinjal. Further, the genotypes could be studied for genetic and specific combining ability, in-order to include valuable landraces in location specific and objective specific breeding programs.
