Rice is grown on 2.5 million ha in Pakistan. The average yield is 2.1 t ha-1. During the 1960s, with the introduction of semidwarf varieties IR6 and IR8, yields doubled and most of the traditional fine-grained aromatic varieties went out of cultivation. However, Basmati 370, a traditional scented variety, survived to a certain extent. Another local aromatic variety, Jajai 77, is very popular with consumers in the province of Sindh. This variety is tall, has weak stems, and is susceptible to lodging. The most logical approach to remove these defects without impairing grain quality is to reduce plant height through induced mutation, a technique that proved successful in improving various agronomic traits in rice (Mustafa et al 1997, Singh et al 1997, Wen et al 1996, Baloch et al 2001).
