GENETIC AND PHYSIOLOGICAL ASPECTS OF SILIQUE SHATTERING IN RAPESEED AND MUSTARD

Rapeseed (Brassica napus L.) and mustard juncea are two important oilseed crops grown worldwide for edible oil meal production, as well as, a source of renewable energy. Silique shattering at the maturity stage is major cause seed yield reduction in brassica. Losses more developing countries due to poor management non-availability combine harvesters. resistance essential achieving good especially Brassica napus. The silique on plants rapeseed mature different phases indeterminate growth habit, which also reason losses. linked with creation dehiscence zone brassica pod. When siliqua wall loses its hydration, along length siliqua, few cell layers separate replum from pericarp tip valves. In zone, it involves collapse walls separation, destruction middle lamella enhanced hydrolytic enzyme activity. To avoid losses, against cultivars. There multiple QTLs discovered that control variance shattering. Previous studies validated process model plant Arabidopsis thaliana was controlled by eight genes. However, their role controlling unknown. Modern tools mutation breeding genetic engineering, CRISPR/Cas9 technology, can be utilized identify mustard, will helpful development silique-shattering
