Marker assisted transfer of drought QTLs and BPH resistance for development of new generation rice
varieties

Rice is the most important cereal food crop of India. Ongoing climate change is predicted to become a major challenge to
sustainable rice production in India in the years to come. Among the different rice-producing states in India, the highest average
rice yields are obtained in Punjab. Rice is cultivated on around 2.9 million ha in Punjab, with total paddy production of 16.6 million
tons and productivity above 5.75 t/ha. The incidence of brown plant hopper has increased tremendously in the past few years causing
significant yield losses, furthermore; deteriorating ground table is also a major concern. The situation will worsen with an increase
in temperature and deteriorating ground irrigation water scenario. PR 121 is a very popular high yielding bacterial blight resistant
variety occupying a large area in the state. It is, however, susceptible to BPH. Attempts are being made to improve this variety for
resistance to drought (abiotic stress) and hoppers (biotic stress) through marker assisted selection. Multiple crossing was done to
combine drought and BPH resistance in PR 121.IR71033-121-15-B (Bph20+Bph21) and IR96321-213-214 (qDTY1.1, qDTY3.1) were
used as donors. Presently, the material is in BC1F2 generation with about 1050 seeds and will be analyzed for target traits.
