Screening bacterial leaf blight (BLB) resistance gene in Nepalese rice gene pool using molecular markers. / Madan Raj Bhatta

Title : Screening bacterial leaf blight (BLB) resistance gene in Nepalese rice gene pool using molecular markers. Material Type: printed text Authors: Madan Raj Bhatta, Editor ; Resham B Amgai, Editor ; Pantha, Sumitra, Author ; Niroula, Raj.K, Author ; Sah, Bindeshwar P., Author ; Bishal G. Tarnang, Author ; Hamal, Shreya S., Author Publisher: Lalitpur : Nepal Agriculture Research Council (NARC) Publication Date: 2012 Pagination: 18-22 p. Languages : English (eng) Keywords: 'durable', 'resistant', 'susceptible', 'pathotype', 'pyramiding' Abstract: Bacterial Leaf Blight (BLB) is the most important yield limiting factor in Nepalese rice. BLB resistance rice varieties are highly demanding in the country. Breeding efforts for developing disease resistant depends on the availability and use of resistant gene donors. Ninety six Nepalese rice accessions were screened using eight SSR markers and one STS marker for presence and absence of BLB resistance gene. We detected BLB resistance gene Xa-10 on two accessions, Xa-13 on six accessions, Xa-7 on 23 accessions, Xa-10 on five accessions, Xa-3 and Xa-4 on 52 accessions, Xa-5 on 25 accessions, Xa-8 on 30 rice accessions. No any rice accessions have Xa-21. Similarly, 17 rice accessions showed three and more than three BLB resistance genes. Presence of Xa-13 on susceptible check variety CNTRL-85033 confirmed that different BLB pathotypes are active in Nepalese rice field and need of gene pyramiding for durable resistance.

Title : Screening Nepalese rice germplasm for blast resistance characters using molecular markers. Material Type: printed text Authors: Madan Raj Bhatta, Editor ; Resham B Amgai, Editor ; Pantha, Sumitra, Author ; Niroula, Raj.K, Author ; Sah, Bindeshwar P., Author Publisher: Lalitpur : Nepal Agriculture Research Council (NARC) Publication Date: 2012 Pagination: 11-17 p. Languages : English (eng) Keywords: 'Magnaporthe' 'resistant' 'susceptible' 'check' 'gene' Abstract: Blast (caused by Magnaporthe oryzae) is the major yield limiting biotic stress for rice farming in Nepal that is prevalent all over the country. Resistant variety for one location becomes susceptible to another location which shows the need of resistant gene pyramiding for yield stability. Identifying blast resistant genes in Nepalese rice germplasm and its use for varietal development is very important. Ninety two Nepalese rice accessions were screened using 12 SSR markers for presence of different blast resistant genes. IR-64 and Sabitri were used as resistant check while Masuli and Jumli Marshi were used as susceptible check. Blast resistant genes Pi-54, Pi-y2(t), Pi-d(t) 1, Pi-z, Pi-a, Pi-k, Pi-yl (t) and Pi-44 were detected on seven, seven, nine, 11, 20 and 28 rice accessions respectively. Eighteen rice accessions showed presence Pi-b and Pi-g(t), 22 rice accessions showed presence of Pi-29 and Pi-11; and two rice accessions showed presence of Pi-ta and Pi20(t). Nepalese rice gene pool doesn't contain resistant gene Pi-d(t)2 and it needs to incorporate from exotic sources. Therefore, many Nepalese rice landraces can be used on marker assisted gene pyramiding program for development of durable blast resistance varieties.
