This work aims to identify the metabolites present in the human Intervertebral Disc (IVD). Metabolomic analysis of human IVD tissue has not been extensively done to date. Knowledge on the metabolites present in the IVD tissue in humans is very limited and many compounds are yet to be identified. In this study, we have carried out the metabolic profiling for human IVD through Gas Chromatography/Mass Spectrometry (GC/MS). This is the first initial study that has compared the metabolites of control and diseased IVD. We have identified 75 different chemical compounds in IVD, and also metabolites that are unique to the diseased IVD, suggesting that some of these metabolites might play a role in disc degenerative disease.Keywords

An experiment was carried out during Rabi, 2013 at Eastern Block of the Central Farm Unit, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India to identify resistant progenies in BC3F1 population against sorghum downy mildew (SDM) incited by Peronosclerospora sorghi. Sorghum downy mildewis one of the most serious diseases in maize producing areas throughout the world. P. sorghi (SDM) is a factor that limits maize production in several countries of Asia (Rifin, 1983). Therefore, there is a need to develop the new maize cultivars with resistance to SDM in order to enhance the yield. In this present study, experiments were undertaken under vigorous artificial infection conditions in spreader row technique during Rabi, 2013 for characterization of responses of 22 back cross progenies to the SDM; in which 16 progenies were confirmed as phenotypically resistant to sorghum downy mildewviz., UMI 79/936- C1-3-2, UMI 79/936-C1-3-4, UMI 79/936-C1-7-2, UMI 79/936-C1-7-7, UMI 79/936-C1-29-8, UMI 79/936-C1-29-9, UMI 79/ 936-C1-29-13, UMI 79/936-C1-29-23, UMI 79/936-C1-29-35, UMI 79/936-C1-29-36, UMI 79/936-C1-67-3, UMI 79/936-C1-67-12, UMI 79/936-C1-67-25, UMI 79/936-C1-101-12, UMI 79/936-C1-101-13 and UMI 79/936-C1-101-14. Resistant lines will serve as basis material for developing single cross and double cross hybrids for resistance against sorghum downy mildew in maize.Keywords

The present investigation was carried out at Department of Millets, Centre for Plant Breeding and Genetics, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India to identify the best performing sorghum downy mildew resistant progeny for agronomical traits. The objective of this study was to identify the better per se performance of the resistant progeny. Twelve biometrical characters of sixteen SDM resistant progenies viz., UMI 79/936-C1-3-2, UMI 79/936-C1-3-4, UMI 79/936-C1-7-2, UMI 79/936-C1-7-7, UMI 79/936-C1-29-8, UMI 79/936-C1-29-9, UMI 79/936-C1-29-13, UMI 79/936-C1-29-23, UMI 79/936-C1-29-35, UMI 79/936-C1-29-36, UMI 79/936-C1-67-3, UMI 79/936-C1-67-12, UMI 79/936-C1-67-25, UMI 79/936-C1-101-12, UMI 79/936-C1-101-13 and UMI 79/936-C1-101-14 were used for mean performance. Studies revealed that among the progenies, UMI 79/936-C1-7-7 and UMI 79/936-C1-7-2 showed better per se performance for yield contributing characters. These two progenies showed highest mean values than the other progenies. It exhibited more mean values than the parents for the characters viz., cob length, cob diameter, number of rows per cob, number of. kernels per row, cob weight, yield per plant, 100 grain weight. Based on the mean values progenies UMI 79/936-C1-7-7 and UMI 79/936-C1-7-2 confirmed as the best progenies.Keywords

From the genetic diversity studies based on 12 morphological characters of 50 soybean genotypes it could be inferred that, the traits seeds per plant and seed yield per plant contributed maximum to the genetic diversity. The clustering pattern revealed that there was no correlation between the geographical diversity and genetic diversity. The clusters IX (JS 90-29 and IC18277) and X (IC93656) were the distant clusters and clusters III (IC 39873 and IC 93751) and VIII (IC 34057 and IC 18736) were the nearest clusters. The clusters IX and I possessed the high mean values for many of the traits studied. With respect to seed yield per plant the clusters IX, VI and I were the superior clusters. The entries viz., JS 90-29 and IC18277 of IX cluster and IC93656 of X cluster can be used in crossing programme for development of good recombinants for seed yield.Keywords

The present investigation was carried out during 2016-2017 to identify the seed development maturation studies in Barnyard millet cv. MDU 1. The results revealed that seeds attained physiological maturity on 50 days after anthesis as evidenced by the maximum panicle length (30.7 cm), fresh weight (31.2 g), dry weight (23.5g), fresh weight of the seeds (23.4g) and dry weight of the seeds (14.5g). The change of colour of panicle and seed from green to dark brown could be considered as a visible index of maturity. The seed quality parameters viz., germination (51 %), shoot length (9.59 cm), ischolar_main length (18.5 cm) and dry matter (0.025 g/10 seedlings) and vigour index (1175) were also maximum at 50 days after anthesis.Keywords
