Abstract

The present study was undertaken to evaluation of variance and mean performance of yield and its associated traits in ten bread wheat genotypes grown in randomized block design with three replication under normal, late and very late sown conditions during rabi 2021-22 at Rajasthan Agriculture Research Institute, Durgapura. The pooled as well as individual analysis of variance revealed that the treatments were highly significant for all the characters under study indicating sufficient genetic diversity present among the parents selected. Environmental factors have negative impact on growth, development and ultimately yield potential of wheat. The mean performance of different studied characters decreased under both (late and very late sown) environmental conditions as compared to normal sown condition indicating delayed sowing influenced by various temperature fluctuations.

Conclusion

The pooled as well as individual analysis of variance revealed that the treatments were highly significant for all the traits under present study indicating wide genetic diversity among the parents. The significant difference for G x E interaction for all studied traits specified a non-linear response of genotypes with changing environment. The mean performance of all the studied characters decreased under late and very late sown conditions. Hence, delayed sowing is the main cause of reducing grain yield due to reduced growth period and facing high temperature conditions during the critical phases of growth and reproduction in wheat crop. Therefore, breeding for higher grain yield should focus on developing cultivars with strong genetic potential, which can survive under high temperature fluctuations.
