Title : Studies on correlation and path analysis in segregating population of Bread Wheat (Triticum aestivum L.)

Abstract :

The experiment of present investigation was conducted to evaluate the 50 wheat genotypes (segregating population lines) along with 5 checks in Augmented Block Design at research farm of department of Genetics & Plant Breeding, school of agriculture, lovely professional university, phagwara, Punjab. The analysis of variance for 50 genotypes (segregating population-F4 generation) and 5 check varieties revealed that the treatments are highly significant for biological yield per plant, days to 50% flowering, days to maturity, ear length, harvest index. The phenotypic coefficient of variation was greater in magnitude than genotypic coefficient of variation for all the characters under study. High values for both the phenotypic and genotypic coefficient of variation was observed in harvest index, biological yield per plant and ear weight. High heritability with high genetic advance was observed for characters such as days to maturity, days to 50% heading, Biological yield per plant, harvest index which indicates improvement in this traits directly done by direct selection.
