Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    GENETICS AND MAPPING OF ANTHRACNOSE RESISTANCE GENE(s) IN COMMON BEAN LANDRACE KRC5
    (CSKHPKV, Palampur, 2015-08-14) Katoch, Abhishek; Sharma, P. N.
    ABSTRACT KRC5, a local landrace of common bean native to Kinnaur region of north western Himalayan state Himachal Pradesh is a well known for its effectiveness against eight pathogen races of C. lindemuthianum viz., 73, 83, 903, 591, 647, 775, 931 and 935. This study reports the identification, mapping and physical delimitation of the chromosomal location of a new anthracnose resistance gene Co-ind from landrace KRC5. The segregation analysis of an F2 progeny of a cross between a susceptible cv. ‘Jawala’ and resistant KRC5, an Andean genotype with three different races viz., 3, 537, 935 suggested that the resistance was conditioned by a single dominant gene. Bulk segregant analysis and recessive class analysis based strategy was used for the mapping of R gene. Preliminary mapping by linkage analysis of 159 F2/ RIL individuals with marker OPF6522 and OPR151136 localized the anthracnose resistance gene on chromosome 7. The R-locus was bracketed between the markers ScOPF6522 and OPR151136 located at a distance of 4.4 and 5 cM, respectively. In this region, six putatively expressed, LRR kinases and serine/threonine kinases (SRK) were short-listed as a potential candidate for the resistance gene identified from KRC5. Out of 178 accession phenotypically evaluated for resistance to race 3 of C. lindemuthianum, only five accessions viz., IC260292, IC265938, IC47839, EC400403 and EC325078 exhibited the presence of Co-ind. In R-gene postulation assay using SCAR markers SCO08, SZ20, SF10 and SAS13, bean accession IC262769 was identified as natural gene pyramid harboring four anthracnose resistance genes (Co-4, Co-42, Co-6 and Co-10) whereas 10 accessions viz., IC260336, IC258273, IC262748, IC47839, EC500328, EC4003433, EC325078 IC265940, IC202271 and IC265938 showed the presence of three resistance genes each. These multigenic accessions represent potential resistance sources and can be effectively utilized either directly as varieties after agronomic evaluation or can be involved in hybridization programmes to transfer resistance in susceptible genotypes after further validation.
