 SUMMARY

Pearl millet is quick growing cereal as compared to maize and sorghum and it produces green fodder in short duration. It is a robust quick growing rainy season grass with large number of tillers, leaves and ear heads. Being tall vigorous with exceptional fodder yielding potential, it is indispensable fodder for the animals inhabitants in arid and semi-arid regions of world. Therefore, the development of quality fodder cultivars and management to meet out the fodder requirement for ever increasing livestock population is imperative, as the quality of the fodder is very important issue with respect to the livestock health status as well as to maximize the animal production of milk and meat. An effort has been made to review the progress done so far towards the development and production of quality fodder of pearl millet. The morphological traits, growth parameters, fodder yield and nutritional quality traits, along with toxic components have been discussed in this review.

 SUMMARY

The genetics of downy mildew was studied in 144 hybrids developed by crossing six A- and their six B-lines with 12 R-lines of pearl millet in a line x tester mating design. The six A- lines 81A1 and 8A1 (A1), Pb 313A (A2), Pb 402A (A3), 81A4 and 81A5 and their corresponding B- lines represented five different systems of male sterility and were very diverse. The 24 parents and the 144 hybrids were grown separately in contiguous blocks in 2R × 2.5 m × 0.45 m in randomized block design with two replications in six environments under natural condition viz., early sown non-cut crop (E1, E4), ratoon crop (E2, E5) and late sown non-ratooned (E3, E6) at Research Farm, CCSHAU, Hisar and two environments in sick plot (SP1, SP2) Department of Plant Pathology, CCS HAU, Hisar. The downy mildew incidence was recorded on all plants in the plot under natural and sick plot after 30 days (stage I) and 60 days (stage II) of sowing. The data on downy mildew incidence (%) were subjected to angular transformation for analysis of variance. The analysis of variance was conducted by developing statistical model involving all genotypes–lines (A-, B-), testers (R-lines), A- x R- and B- x R-hybrids, environments and all possible interactions. The combining ability analysis was carried out following line x tester model. The genotypes, parents, lines (A-, B-), testers (R-lines), A- x R- and B- x R-hybrids differed significantly at both the stages but A- vs. B- lines and A- x R- vs.  B- x R-hybrids contrasts did not differ significantly showing no role of cytoplasm in downy mildew vulnerability. The significant differences among lines, testers and lines x testers (hybrids) indicated parental and hybrids variation for general combining ability (gca) and specific combining ability (sca) variances and effects, respectively, under natural as well as sick plot at both the stages. The fixed effect mean square variances due to general combining ability (gca) and specific combining ability (sca) revealed that magnitude of sca variances exceeded at 30 DAS and that of gca variances excelled sca variances at 60 DAS indicating that final selection should be carried out at latter stage. The lines Pb. 402A3 and Pb. 402B3 with negative gca effects combined significantly better for downy mildew resistance at both the stages. The other lines combined poor to average with most of the non significant gca effects.

 Summary

A field experiment was conducted with nine treatment combinations [three advance hybrids; HHB 94, HHB 197 and HHB 223 and three levels of  ZnSO4 i. e. control (T1), application of 10 kg ZnSO4 as basal + 0.5 per cent as foliar spray 30 days after sowing of the crop (T2) and application of 20 kg ZnSO4/ha as basal (T3)] in factorial randomized block design with three replications during kharif seasons of 2010 and 2011 in the Bajra Section, Department of Genetics & Plant Breeding, CCS Haryana Agricultural University, Hisar. The hybrids showed variable response to zinc treatments. The hybrid HHB 94 took 6 to 8 more days for 50 per cent flowering than HHB 223 and HHB 197. The increase in the green fodder yield was to the tune of 11.1 and 18.8 per cent in HHB 94, 9.6 and 17.9 per cent in HHB 197 and 10.2 and 17.6 per cent in HHB 223, respectively, with the T2 and T3 treatments, respectively, over  the control. On mean basis, HHB 223 showed 23.4, 18.8, 18.1 and 13.2 per cent more earhead, grain, green fodder and dry fodder yields, respectively, than HHB 94 and 5.3, 7.0, 7.1 and 4.5 per cent, respectively, as compared to HHB 197. The grain yield was increased by 10.6 and 9.0 per cent, whereas dry fodder yield to the tune of 15.5 and 10.7 per cent by T3 and T2 treatments, respectively, than the control (T1). The results also indicated that basal application of ZnSO4 was slightly better than combination of basal and foliar application.

SUMMARY

 A field experiment was conducted at Agricultural Research Station, Fatehpur-Shekhawati in three consecutive rainy (kharif) seasons of 2006-08) to study the effect of hydrogel on yield and water use efficiency in pearlmillet. The soil of the experimental field was sandy loam, low in available nitrogen (168 kg/ha), medium in available phosphorus (21 kg/ha) and high in available potash (301 kg/ha) with 0.46 per cent organic carbon and alkaline (pH 8.2) in reaction. The experiment consisting of six treatments was conducted in randomized block design with four replications. The study revealed that effective tillers/plant, ear length, grain weight/earhead and test weight were significantly influenced by seed treatment with hydrogel. The grain, stover yield and WUE were also significantly influenced by the hydrogel application. The highest increase in grain yield was noted with seed coating with 20 g hydrogel+TU+DMSO followed by 20 g hydrogel, 10 g hydrogel+TU+DMSO and 10 g hydrogel per kg seed.

SUMMARY

 Seeds of berseem variety Mescavi were treated with three doses (50, 70 and 100 kR) of gamma rays and three doses (0.1, 0.3 and 0.6%) each of methyl methane sulphonate (MMS), diethyl sulphonate (DES) and sodium azide (SA) to study the induced genetic variability, heritability and genetic advance for plant height and tillers per plant, the main components of fodder yield.  The estimates of genotypic and phenotypic coefficients of variation were higher for tillers per plant in comparison to plant height which were indicative of induction of wider genetic variability for this trait due to mutagenesis. The estimates of high heritability (broad sense) coupled with high genetic advance (% of mean) were observed for plant height in treatments of 70 kR gamma rays and 0.6 % MMS, whereas for tillers/plant medium heritability with high genetic advance was recorded for all the three treatments of MMS.

 SUMMARY

Correlation studies revealed that the characters viz., ear girth and effective tillers per plant exhibited significant positive phenotypic correlations with grain yield per plant, while protein had positive but non-significant. Path coefficient analysis based on genotypic correlation showed high positive and direct effects on grain yield per plant by ear girth and days to 50 per cent flowering. The high association of ear girth and effective tillers per plant with grain yield per plant; their large direct effects suggested maximum emphasis in selection for improvement of grain yield in pearl millet.

Abstract

The present investigation in forage sorghum {Sorghum bicolor (L.) Moench} was carried out to study the magnitude of heterosis and inbreeding depression in fifty four crosses (F1s) and their F2s made by crossing nine sudan grass pollinators with six cytoplasmic male sterile lines in a line x tester mating design. Observations were recorded on yield and quality traits viz. plant height, stem diameter, number of leaves per plant, leaf length, leaf width, number of basal tillers, shootfly infestation, total soluble solids, HCN content, protein percent, green and dry fodder yield. Variable magnitude of three type of heterosis (better parent, mid parent and standard) were observed for different cross combinations for all the traits. Based on per se performance and heterotic response for green and dry fodder yield, two best crosses identified were ICSA-271 x UTMC-523 and ICSA-271 x 700R. Response of inbreeding depression was significant in positive direction for most of the characters except leaf width, number of basal tillers, total soluble solids, HCN content and protein percent.
