    Abstract

    Pearl millet grains are valued as human food while its dry stover makes important livestock ration in crop–livestock farming system. Interspecific hybrids between cultivars of pearl millet Pennisetum glaucum (L.) with 2n = 2x = 14 and its wild relative Napier Grass Pennisetum purpureum (K.) Schum with 2n = 4x = 28, which have multicut behaviour, perennial nature, high biomass and drought tolerance traits for crop improvement, were obtained by cross hybridization. Several hybrid progenies were obtained and then examined based on the morphological traits at RVC, BAU, Ranchi. The F1 seed of each combination was harvested at maturity and the F1 seed was planted on raised nursery bed to remove the bajra like plants. The row to row and plant to plant spacing was 60 cm. All the recommended cultural practices were followed to raise the healthy crop. Thin napier lines were procured from PAU, Ludhiana. Several yield and yield and yield attributing traits were recorded The highest no. of slips were obtained by LN 3 (24) followed by LN 1 (20). In bajra, 10 forage A lines (male sterile lines) and 18 forage pollinators (OPVs) (recurrent lines) were procured from ICRISAT, Hyderabad. The characters recorded were days to 50% flowering, plant height, no. of tillers/plant, spike length and green fodder yield (q/ha). In case of male sterile line, the highest green fodder yield (q/ha) was recorded by ICMA 00444A4 (545 q/ha) followed by ICMA 07999A5 (430 q/ha) while in case of Forage pollinators (OPVs), the highest green fodder yield (q/ha) was recorded by ICMV 05222 (684 q/ha) followed by ICMV 1710 (623 q/ha). Different Hybrids were developed from crossing of Bajra x Bajra and Bajra x Napier on two different dates of sowing. The interspecific hybrids between Bajra x Napier in first date of sowing (16.8.20) were BxN1 (384 q/ha) BxN2 (379 q/ha) and BxN3 (456 q/ha). The Number of crosses developed between Bajra x Bajra on two different dates of sowing i.e. 16.8.20 and 30.8.20. Several crosses were developed. Out of them, B2xB23 (656 q/ha) recorded highest yield followed by B2xB25 (546 q/ha). In the second date of sowing B6xB12 (634 q/ha) recorded highest yield followed by B2xB23 (578 q/ha).
