Abstract

Thesis title: Investigations on Brown Rust (Puccinia Recondita f. sp. tritici Rob. ex. Desm.) of wheat and it s Integrated Disease Management newlineIn India, wheat (Triticum aestivum L.) is a staple food. Rust caused by. Puccinia Recondita f. sp. tritici Rob. ex. Desm. (brown rust) is the most destructive and one of the most common diseases of wheat worldwide. It probably results in higher total annual losses worldwide because of its more frequent and widely distributed diseases of wheat in India and elsewhere that affects its yield potential. Although, chemical control of these diseases is known but is not economic and environmental friendly to be used on a large scale. Due to the frequent break-down of major resistance genes in recent years and difficulties in quick replacement of susceptible wheat varieties led to the investigations of other forms of disease resistance like adult plant resistance(APR) and slow rusting which are considered as more durable. The present investigations was carried out with the following objectives: 1. Survey in different region of Uttar Pradesh newline newline
