摘要

本研究涉及评估配合力效应和杂种优势分组，以提高亲本选择对成功杂交发展的效力。通过对26个不同玉米自交系与HKI 323和HKI 1105两个试验者的交配设计，共产生52个F1杂交种。根据特异配合力（SCA）效应和特异和一般配合力（HSGCA）效应，将26个玉米自交系划分为不同的杂种群。无壳玉米产量的SCA效应和HSGCA分别将自交系分为五组和四组。这是首次在SCA和HSGCA方法的基础上，对考虑BCY的玉米种质进行杂种优势分组研究。通过异源分组产生的信息可用于衍生新的自交系和开发不同的异源组合，以便在育种计划中进一步利用。

Heterotic grouping of Indian baby corn lines based on combining ability

The present study involved estimating the combining ability effects and heterotic grouping to increase the efficacy of parental selection for successful hybrid development. A total of 52 F1 hybrids were generated by Line × Tester mating design by crossing 26 diverse maize inbred lines with two testers, namely, HKI 323 and HKI 1105. The 26 baby corn inbred lines were classified into a different heterotic group based on the specific combining ability (SCA) effects and heterotic groups specific and general combining ability (HSGCA). The SCA effects and HSGCA of baby corn yield without husk (BCY) classified the inbred lines into five and four groups, respectively. This is the first study of heterotic’s grouping for baby corn germplasm considering BCY based on SCA and HSGCA methods. The information generated through heterotic grouping may be used to derive new inbred lines and develop different heterotic combinations for further utilization in breeding programs.
