Abstract:
Path analysis over three seasons viz., Rabi, summer and kharif carried out utilizing 45 single cross hybrids derived from 10 inbred lines of maize for morpho-physiological and yield components on kernel yield revealed that number of kernel rows cob^-1, number of kernels row^-1, 100 kernel weight, cob length and cob girth exerted consistently higher positive direct effects on kernel yield in all the three seasons. All these characters also showed consistent positive indirect effects on kernel yield besides significant and positive associations among themselves and with kernel yield. The characters viz., days to 50% tasseling, days to 50% silking, anthesis-silking interval, days to maturity, plant height, SPAD meter readings, specific leaf area, specific leaf weight and harvest index had inconsistent direct effects either positive or negative on kernel yield over seasons. Number of kernel rows cob^-1, number of kernels row^-1, 100 kernel weight, cob length and cob girth which showed consistently higher positive direct and indirect effects and positive and significant associations among themselves and with kernel yield may be considered, while making selections foe higher yields in maize.
