Abstract:
The current study was carried out for the thirty advanced lines of wheat, evaluated under late sown condition Rabi 2014 in a randomized block design for seventeen traits under wheat improvement project at seed breeding farm JNKVV, Jabalpur. Analysis of variance resulted into significant differences among all the studied traits. Genetic variance were found highest among the traits viz; harvest index followed by the number of grains plant^-1 and plant height. The value of PCV and GCV were high for the characters viz; number of effective tillers plant^-1 number of ears plant^-1, number of grains plant^-1, ear weight, yield plant^-1 and the number of tillers plant^-1. The remaining characters exhibited moderate to low value of PCV and GCV estimates. Estimates of heritability and genetic advance were observed higher for the characters viz., number of grains ear^-1, number of grains plant^-1, ear weight, peduncle length, yield plant^-1, number of leaves plant^-1, 1000 grain weight, harvest index, and biological yield plant^-1. This study showed that broad-sense heritability showed a high level of genetic control above examined traits. It is concluded that more fertile tiller number and ear weight of main spike are major yield contributing factors in selecting high yielding wheat lines.
