Abstract:
An experiment was laid out during Rabi 2020-21 to evaluate the F₄ generations belonging to the crosses UAS BW 13356 × HD 2967 and WH 1022 × K 9107 in wheat for Nitrogen use efficiency and related traits. The F₄ progenies were derived from the parents with varied response for N use efficiency. The F₄ progenies showed significant genotypic variance for most of the characters studied. The Nitrogen use efficiency and related traits showed significant genotypic variance. The genotypic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), heritability and genetic advance as percent of mean was found to be high for N use efficiency and related traits. Hence, existence of sufficient genetic variability shows that breeding for Nitrogen use efficiency is expected to be successful in wheat.
