Online Published on 22 January, 2024. Abstract An experiment was carried out during Kharif 2020 at wetland farm of Sri Venkateswara Agricultural College, Tirupati using 30 inbred lines of maize to assess the trait association for 16 yield and yield attributes. It revealed that ear length, number of kernels per row, plant height, ear girth, SPAD chlorophyll meter reading, 100 kernel weight, number of kernel rows per ear, specific leaf area, harvest index and tassel length had notable positive correlation with kernel yield per plant suggesting that selecting these characters simultaneously lead to an increase in kernel yield per plant. Path analysis revealed a significant and positive direct influence of ear length on the kernel yield per plant. Hence, ear length could be considered during selection in maize for improving kernel yield. Top Keywords Maize, Correlation, Path analysis, Inbred, Direct effects. Top |
