Study of the fodder quality parameters of Grewia laevigata Vahl., was undertaken with a view to harness its potential in future breeding programme and to encourage the farmers to plant the species to enhance fodder productivity. The study was conducted in the Shiwalik region of two districts of Himachal Pradesh to estimate leaf fodder nutritional value and its variation at different sites. Nutrient contents and leaf proximate composition were worked out along with their correlation co-efficient, heritability and genetic gain. The study concluded that significant differences in mineral nutrients, except for potassium and also for proximate principles, showed variability between the populations in different localities. Mineral nutrients and proximate principles exhibited phenotypic variability higher than the genotypic ones with very less differences between the two levels. Thus indicating that these are least influenced by the environmental parameters. Hence selection of superior genotypes in 'nallah' locations is most suitable in comparison to other locations for further multiplication and breeding programmes for increasing fodder productivity.Keywords

Studies were undertaken to evaluate half-sib progenies in Pinus roxburghii Sargent at the age of about 12 years. Thirty three families were taken for study randomly out of a total of 58 families planted in the test n randomized complete block design to identify the promising selections to be used in future improvement programme. Eight growth characters viz., plant height, diameter at breast height, current year height increment, mean internodal length, specific gravity of branch wood, fresh weight of spur, dry weight of spur and per cent dry matter in spur were studied. Heritability (within family, half-sib family and individual tree basis) and genetic gains (family selection and within family selection) were also determined. Significant differences in all traits at half-sib and within families levels were observed except for the mean internodal length. Charet Mansu P4 (34) family showed overall best performance and may be used for further improvement work. Genetic gain of within family selection (GW) was found to be more than genetic gain of family selection (GF) for almost all characters. Most of the half-sib families exhibited better growth rates than predicted by yield tables for Pinus roxburghii at best sites which indicates that all the selected families are superior in growth traits.Keywords

Seabuckthorn is a wonderful plant for the afforestation and ecological rejuvenation of the cold desert areas of Himalayas where plantations of poplars, willows and robinia have not given very encouraging results. It has the potential to economically transform these harsh and marginal areas plagued by low productivity. Keeping in view, almost complete lack of information in India on regeneration through seed the present investigation was carried out to standardize various presowing treatments in two species of Sea buckthorn in the cold desert of Himachal Pradesh. Different presowing treatments were hot water (80DC for 10 minutes), conc. H2S04 (20 minutes), cold water for 2,4 and 6 days, cow dung heap for 2 days and control. In case of Hippophae rhamnoides, the best presowing treatment was found to be cold water soaking for 6 days which resulted in the highest germination per cent (93.33), per cent survival (73.33), growth index (69.78) and SVI (8502.36). However, for H. salicifolia soaking treatment in hot water at 80DC for 10 minutes was found to be the best and resulted in the highest germination per cent (76.66), per cent survival (60.00), shoot length (45.6 cm), ischolar_main length (70.9 cm), growth index (39.90) and SVI (8930.89) and ranked first.- Effect of Growth Regulators and Seasons on the Propagation of Different Seabuckthorn Species Through Cuttings in Cold Deserts of Himachal Pradesh

Juvenile growth traits were studied in the recently introduced clones of Salix species from twelve countries including Croatia, Sweden, Italy, Hungary, Turkey, Japan, Yugoslavia, UK, Belgium, New Zealand, Germany and USA which were screened in the nursery by applying 'augmented completely randomized design' with three check clones (SI-64-017, SI-63-007, Kashmiri willow). Significant differences were recorded for morphological traits among test clones and test verses check clones except in leaf length among test clones and volume index, leaf length and petiole length among check verses test clones. The clones SI-63-016, J-799, PN-722, NZ-1002, PN-733, PN-731, SN-2, S × 61, 194 and 084/03 were found superior to check clones for the growth traits viz., plant height, basal diameter and volume index. Heritability in broad sense (91.08 %) and genetic gain (75.24 %) was found highest for leaf breadth and volume index, respectively. Maximum positive and significant correlation coefficient (0.959) was recorded for basal diameter with volume index. Principal component analysis through correlation matrix revealed that three out of eight components contributed 85.03 per cent of the overall variation out of which the first principal component (λ=3.086) explained 38.57 per cent of the variance weighted maximum (0.937) by volume index. These promising clones selected under the present study will be further tested under multi-location trials to study the genotype x environment interaction at different sites for analysis of suitability of clones.Keywords

Variability studies in fodder quality parameter in Anogeissus latifolia Wall (Family-Combretaceae) was undertaken in four districts of Himachal Pradesh viz., Solan, Sirmour, Kangra and Una at eight sites under different elevations in three diameter classes viz., 10-20 cm (small) 20-30 cm (medium) and 30-40 cm (Large). Proximate principles of leaf fodder in S4 (Chaoban, Distt Sirmour) and S1 (Jadli, Distt Solan) exhibited maximum variation in almost all nutritional traits. Study concluded indicating that direct selection from the altitude ranging between 600 m to 1000 m amsl in large diameter class (30-40 cm) is recommended for the improvement of species and to have superior genetic gains for further breeding works.Keywords

Twenty four populations of Sapindus mukorossi Gaertn. scattered over a wide range upto 1500 m elevation in Himachal Pradesh were evaluated to observe variation in seed oil contents and seed oil quality traits. Significant variation among different populations were observed for per cent seed oil content and non significant for oil quality traits. Maximum oil content was recorded in Garsa (18.92%) population. D.B.H classes did not show distinct variation for seed oil content and oil quality traits. Study concluded that on an average, the populations of Garsa (Kullu Forest Division) of Himachal Pradesh was found to be best over all other populations for both the traits. This investigation will be useful for further improvement of the species for improved genetic gain.Keywords
