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.

    STABILITY ANALYSIS FOR POD YIELD AND COMPONENT TRAITS AND VALIDATION OF POWDERY MILDEW RESISTANCE IN GARDEN PEA
    (CSKHPKV, Palampur, 2019-03-08) Rana, Chanchal; Sharma, Akhilesh
    The experimental material comprised of 48 genotypes was evaluated in Randomized Complete Block Design with three replications at five diverse locations by creating seven environments during 2016-17 and 2017-18 viz., Bajaura (E1), Dhaulakuan (E2), Una (E3), Palampur (E4) and Natural Farming at Palampur (E5) during winter 2016-17, Kukumseri (E6) during summer 2017 and Palampur (E7) during winter 2017-18. The advance breeding lines SP-3 (83.35g) followed by SP-6 (79.45g) and SP-22 (76.90g) significantly produced more pod yield than check Pb-89 with an increase of 20.2%, 14.6% and 10.9%, respectively over the environments which was mainly attributed to their desirable performance for important pod characteristics. They also showed comparable performance for total soluble solids, ascorbic acid and protein content besides having long, lush green pods. Joint regression analysis revealed that G × E (linear) was significant for days to first picking, plant height, harvest duration pods/plant, pod yield/plant, average pod weight and protein content, whereas non-linear component was significant for all the traits. Of the 48 genotypes, only seven genotypes including the high yielding lines SP-6 and SP-22 showed stability for pod yield based on Eberhart and Russell model. Both these genotypes also showed stability across environments for majority of the economic traits. G+GE biplot model extrude that Dhaulakuan was the most representative and discriminating environment for pod yield i.e. suitable for selecting generally adapted genotypes.‘Which won where’ polygon view also showed that SP-3, SP-6 and SP-22 were in general stable across the environments for pod yield and other desirable traits. Screening for powdery mildew resistance under field and in-vitro conditions revealed that 10 genotypes viz., SP7, SN-1, SN-6-1, SN-7-1, SN-2, SN-5-2, SN-6-2, SN-21 and SP-28-1 along with Palam Sumool were found resistant for powdery mioldew disease. In addition, 27 lines including SP-3, SP-6 and SP-22 were moderately resistant whereas check Azad-P1 was highly susceptible. It can be concluded that high yielding lines viz., SP-3, SP-6 and SP-22 showed stability for majority of the desirable traits across the environments along with moderate resistance to powdery mildew disease both under field and in-vitro conditions and thus, can be exploited for commercial cultivation.
