“…Sundaram et al (2009) again showed that NILs possessing a combination of xa13 and Xa21 in the background of rice variety, Triguna showed high level of resistance to Xoo. Combination of BB resistance genes, xa13 and Xa21 in the background of popular basmati rice variety, Pusa Basmati 1 provided broad-spectrum resistance to BB (Joseph et al, 2004). It can be concluded from the study that 2-gene pyramided lines of popular rice varieties MTU 1010 and JGL 1798 performed better compared to lines possessing single BB resistance gene and can be deployed in the state of Telangana and Andhra Pradesh to combat bacterial blight disease of rice.…”

“…Some of the major BB resistance genes which have been widely used in gene-pyramiding programs in India are xa13 and Xa21 . Several studies in India have reported that combination of Xa21 and xa13 provides high level and broad spectrum resistance to Indian Xoo population (Joseph et al, 2004;Mishra et al, 2013;Mondal et al, 2014;Ellur et al, 2016a). Keeping in view the broad spectrum effectiveness of Xa21 and xa13 combination, these two BB resistance genes were selected for pyramiding in these two popular rice cultivars.…”

Cottondora Sannalu (MTU 1010) and Jagtial Sannalu (JGL 1798) are widely cultivated rice varieties in Telangana and Andhra Pradesh and very well-accepted among the farmers because of their high yield, slender grain and preferred cooking quality. Despite being popular, these varieties are susceptible to different pests and diseases including bacterial blight (BB), caused by Xanthomonas oryzae pv. oryae (Xoo). Two BB resistance genes viz., xa13 and Xa21 were introgressed in these two varieties using marker assisted backcross breeding. Homozygous lines possessing BB resistance genes xa13 or Xa21 and their combination were evaluated for BB resistance with multiple Xoo isolates under controlled condition in glass house and also at different hot spot locations in the states of Telangana and Andhra Pradesh, India. Both the recurrent parents (MTU 1010 and JGL 1798), TN1 (susceptible check variety) and Improved Samba Mahsuri (resistant check variety) were also subjected for resistance evaluation. All the gene-pyramided lines were highly resistant to BB both under glasshouse and field condition. Individually, BB resistance gene xa13 showed higher level of resistance than Xa21. The resistance level was higher in the lines possessing both the BB resistance genes in comparison to the lines possessing single BB resistance genes. The results showed that combination of BB resistance genes xa13 and Xa21 can provide broad level of resistance against BB in Telangana and Andhra Pradesh.

“…The details of SNP marker of rice are available in OryzaSNP and it needs minimum quantity of DNA, automation of genotype and largest amount of DNA polymorphism (Huq et al, 2016;kurokawa et al, 2016). Newly developed SNP markers are amenable to validation and once it is validated, it will be useful in molecular breeding approaches (Agarwal et al, 2016) (Joseph et al, 2004). During each backcross generation, plants which had bacterial resistant gene in the background of Pusa Basmati 1 was selected and a series of field trials were conducted.…”

Bacterial blight is one of devasting disease in almost all rice growing countries. The most effective, economic and environmental strategy for control of this disease is to develop rice varieties with genetic resistance. However, new pathotype has overcome single gene for resistance in the new cultivars. So, plant breeders are concentrating to develop high yielding varieties with durable resistance using novel technologies. Molecular marker technology has progressed tremendously in the past decade for genetic improvement of field crops. Molecular markers can improve efficiency of breeding in different ways for trait in segregating population like identify plants with target gene in maximum recovery portion of recurrent parent. The transfer of two or three genes into single variety with the help of molecular marker is expected to lead to more durable resistance. Thus, thus review describes progress made in the development of bacterial blight resistance rice varieties using Marker Assisted Selection.

“…Recently, MAS has been extensively used to select the lines containing the BB resistant genes viz. xa5, xa13, and Xa21 using STS, CAPS and SSR markers (Chen et al, 2000;Chen et al, 2001;Sanchez et al, 2000;Singh et al, 2001 andJoseph et al, 2004).…”

BRRI dhan52 is a uniquire submergence tolerant rice variety containing prominant genetic background of BR11, a mega rainfed lowland rice (RLR) variety of Bangladesh, but is susceptible to bacterial blight (BB) caused by Xanthomonas oryzae pv. oryzae (Xoo). The variety is considerably popular in the southern part of Bangladesh due to its high yield in flash flood condition and comparatvely medium slender grain. Molecular markers linked to BB resistance genes (Xa genes) and submergence QTL (SUB1) were utilized in a marker-aided selection program to develop elite breeding lines with broad-spectrum resistance to bacterial blight. Sequence tagged site (STS) and simple sequence repeat (SSR) markers were essentially used to detect the genes for BB and submergence as well. In backcross generation, markers closely linked to Xa21 and SUB1 QTL were used to select desirable plants possessing these resistance genes (foreground selection) and microsatellite markers polymorphic between donor and recurrent parent were also used to select plants that have maximum contribution from the recurrent parent genome (background selection). In BC1F1 generation, three best plants consiquently were selected from previously selected ten double heterozygous (Xa21 and SUB1 QTL) plants. The percentage of recipient genome recovery in the best plant 1, 2 and 3 were 78.7%, 75.83% and 75.4%, respectively. Eventually this work illustrates the successful application of marker-assisted breeding for introgression of bacterial blight resistant gene into a rice variety of Bangladesh.
