Genetic variability, correlation and path analysis was carried out for yield and yield components in 542 F3 progeny lines developed by crossing JK8 x Peddasame (purple late) in little millet during Kharif 2015. Seven biometrical characters were studied for estimating genotypic co-efficient of variation (GCV), phenotypic co-efficient of variation (PCV), genetic advance, heritability (broad sense), genetic advance as per cent of mean, correlation co-efficient and path co-efficient among themselves. High GCV and PCV were observed for number of productive tillers per plant and per plant yield. High heritability was observed for plant height and 1000 seed weight. Number of productive tillers per plant showed maximum genetic advance as per cent of mean followed by grain yield per plant, panicle length and plant height. High heritability coupled with moderate genetic advance as per cent of mean were observed for plant height and 1000 seed weight. Grain yield per plant possessed significant positive correlation with plant height, panicle length, number of productive tillers per plant and 1000 seed weight. Number of productive tillers per plant imparted maximum direct effect on grain yield followed by panicle length, 1000 seed weight and plant height.Keywords

- Resource Sharing and Networking: An Overview

Resource sharing is a method of overcoming the limitations of the individual libraries in respect of their resources by way of co-operation and coordination among the participating libraries. On demand, each participating library should voluntarily come forward to share its existing resources with the other participating libraries. Thus, in this system, each library is both a giver and a receiver. There is, thus, an imperative need to develop a spirit of co-operation among the librarians, information scientists and documents lists. This spirit of sharing the resources would entail the participant libraries in a system to benefit for advancing their individual goals and objectives.
Resource sharing implies sharing of library resources by participating libraries among themselves on the basis of mutual co-operation. This can be implemented in the areas of documents, manpower, facilities, services, building, space or equipment. The advantage of this cooperative venture is that the users of participating libraries can make use of the resources of not only his own libraries but also those of all the other participating libraries. Thus the total collection of all the participating libraries will be accessible to their users. In a way, libraries can improve their library collection and extend their library and information services to a larger user community.

The evolution of traditional library collections to digital or virtual collections has given new dimension. The Internet, Web environment and associated sophisticated tools have given a new dynamic role to play and serve the new information based society in better ways than previously. Because of the powerful features of Web i.e. distributed, heterogeneous, collaborative, multimedia, multi-protocol, hypermedia-oriented architecture, World Wide Web has revolutionized the way people access information, and has opened up new possibilities in areas such as digital libraries, virtual libraries, scientific information retrieval and dissemination. For above list there is a new addition called “cloud computing”, it is a new technology which uses Internet and central remote servers to keep up data and applications. The article gives an overview of limitless scope of cloud computing using internet and web, the role of cloud computing in sharing of information resources through internet and web environment especially as intermediary, facilitator, knowledge manager and shifter of information resources is also described.

An investigation was carried out in F3 and F4 segregating generations of little millet to study gene interactions and correlation for yield and its component traits during Kharif 2015 and summer 2016 at UAS, GKVK, Bengaluru. Most of the characters studied were positively skewed and were being governed by several genes indicating quantitative inheritance. Characters seed yield per plant, number of productive tillers per plant and days to maturity were positively skewed indicating complementary gene action hence, to maximize the genetic gain in these characters require intense selection from the existing variability. Panicle length showed negatively skewed distribution indicating duplicate gene action hence, genetic gain will be rapid under mild selection. Seed yield and associated characters showed leptokurtic distribution indicated the involvement of few genes in inheritance of these traits. Seed yield per plant had significant positive association with days to 50 per cent flowering, plant height, number of productive tillers per plant, panicle length and days to maturity. This indicates that selection could be practiced for these component characters to increase seed yield. Variance for majority of the characters has decreased in F4 over F3 generation indicated over the generation variability in population has decreased due to increase in homozygosity.Keywords
