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.

    Hybridization potential of Chinese spring wheat with indigenous cultivated barley and haploid induction efficiency of their derivatives following chromosome elimination- mediated systems
    (Palampur, 2021-11-02) Chopra, Neel Kamal; Chaudhary, H. K.
    The research endeavour entitled “Hybridization potential of Chinese spring wheat with indigenous cultivated barley and haploid induction efficiency of their derivatives following chromosome elimination- mediated systems” was executed in the Department of Genetics and Plant Breeding, CSK HPKV, Palampur during the years 2019-20 and 2020-21 with the goal to work out relative efficiency of Chinese spring wheat × cultivated indigenous barley and induce haploids from the BC1F1 generation of Chinese spring wheat × cultivated indigenous barley through Imperata cylindrica and maize- mediated chromosome elimination technique of doubled haploidy breeding. The material for present investigation comprised of two bread wheat genotypes; Chinese spring wheat and C306, ten potential barley landraces collected from north- west Himalayan regions and their F1s & backcross derivatives. During rabi 2019-20, hybridization work was carried out using wheat genotypes as female parent and barley genotypes as male parent followed by estimating the frequency of seed setting induced by the barley genotypes in wheat parental lines. The first filial generation produced after hybridization was sown at HAREC, Kukumseri to deduce the frequency of seed setting for the formation of backcross generation. Chinese spring wheat genotype performed better than C306 for development of F1s while Barley 3 and Barley 10 reported significantly higher response for hybridization with Chinese spring wheat and C306, respectively. The mean seed setting frequency recorded for the development of F1 and BC1F1 generation was 0.76% and 16.34% in Chinese spring wheat while 0.37% and 20.04% in C306, respectively. For all the parameters of haploid induction viz., pseudoseed formation, embryo formation and regeneration, significant differences were recorded in all the wheat/ barley derivatives depicting genotype specificity for haploid induction. Based on statistical analysis, it was revealed that relative efficiency of I. cylindrica was higher than maize for haploid induction. C306 performed better than Chinese spring for induction on haploids following I. cylindrica mediated- chromosome elimination technique. Bread wheat genotypes performed better than the backcrosses following F1 and F2 genotypes towards haploid induction parameters. Barley 4 and Barley 9 performed better for hybridization and haploid induction in Chinese spring wheat and C306, respectively than other barley landraces. This attempt of hybridizing wheat with barley; producing haploids from their backcrosses especially BC1F1s, which can be transformed into double haploids by colchicine treatment has opened the dimensions with enhanced opportunities of genetic upgradation of wheat utilizing gene(s) from barley
