GENETIC STUDY AND ASSOCIATION OF ADVANCED WHEAT GENOTYPES FOR YIELD AND ITS ATTRIBUTING CHARACTER UNDER IRRIGATED TIMELY SOWN CONDITION
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 4
Abstract
The present investigation was carried out for the thirty advanced genotypes of wheat, evaluated under timely sown condition Rabi 2012 in a randomized block design for seventeen characters under wheat improvement project at seed breeding farm JNKVV, Jabalpur. Analysis of variance revealed significant differences among all the studied character. Genetic variance were found highest among the characters 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. Number of grains plant-1, the biological yield plant-1, number of leaves plant-1 and 1000-grain weight were the characters associated significantly and positively with grain yield at the phenotypic level. Therefore, positive correlation coefficient between any two characters suggested that they can improve simultaneously and improvement in one will automatically improve the other.
