Sixty three genotypes of eggplant were studied to estimate variability, heritability and genetic advance at the department of Vegetable Science, Punjab Agricultural University, Punjab. The PCV and GCV were high (during both seasons) for traits like fruits per plant, fruit weight, pseudo style flowers, long style flowers, short style flowers, medium style flowers, flowers per inflorescence, fruit setting and fruit length. Heritability and genetic advance were also high for all these traits indicating the possibility of selection to improve these characters. Hence it could be concluded that improvement by direct selection in eggplant was possible for the traits like fruits per plant, fruit weight, fruit yield per plant, long style flowers, medium style flowers, seeds per fruit.Keywords

Zigbee Network has potential applications in the field of automation, health care and industry. This network is WPAN based on IEEE 802.15.4 standard having low data rate, low complexity, low cost and low power consumption and long battery life. Zigbee network structure supports both fixed and mobile devices. So in order to achieve reliable and seamless connectivity, robust mobility management is very challenging because of limited size and capabilities of its constituent nodes. This network mainly investigates the effect of mobility on the performance un-interrupted data transfer. The performance evaluation has been done here for cluster tree and cluster mesh topologies in terms of standard QoS parameters like throughput, load and delay. Moreover the effect of mobility has been investigated by varying packet size.
