Studies of character association in wheat (triticum species)
2017
The experiment was carriedout during Rabi 2003–04 at the Agricultural Research Farm R B S college Bichpuri (Agra). The experiment revealed that grain yield was significant positively correlated with number of effective tillers (0.626) followed by length of spike, 100 seed weight, number of seeds per spike and significant negative correlated with days to maturity (0.610) followed by plant height, number of spike-lets per spike at phenotypic level and also positive significant correlated with number of effective tillers (0.628) followed by length of spike, number of seeds per spike, 100 seed weight and significant negative correlated with plant height followed by days to maturity, number of spike-lets per spike at genetic level. Being a complex character grain yield per plant is depending upon a number of yield contributing factors. Therefore the genetic makeup can be better known through components. The correlation coefficient gives an idea about the various associations existing between yield and yield components.
