"Sorghum Is widely grown in the Semi-Arid Tropics (SAT) for food, feed, fodder arid forage.\r\nAlthough India and Africa represent the major sorghum growing areas, grain yield levels are low\r\ncompared to those in the developed world. An attempt Is made to summarize the relevant research\r\nthrusts that have implications on Improving sorghum genetically.\r\nThe cultivated taxa, Sorghum bico lo r (L.) Moench with 2n = 20 were evolved and domesticated\r\nin North Eastern Africa. Based on spikelet characters, they are grouped into five racescaudatum,\r\nguinea, kafir, durra and bicolor and ten hybrid races. The cultivated forms probably\r\narose from S. verticihiflorum. Nearly 35000 landraces collected from 87 countries are being maintained\r\nat ICRISAT Asia Center, Hyderabad, India. -\r\nInitial attempts to breed sorghum were in understanding inheritance of several morphological traits\r\nbased on mendelian factors and breeding for specific adaptation. The establishment of All India\r\nCoordinated Sorghum Improvement Project in 1970, and International Crops Research Institute for\r\nthe Semi-Arid Tropics with sorghum as one of its mandate crop in 1972 and the initiation of conversion\r\nprogram in USA in early part of 1960s demonstrated that wide adaptability and high yield can be\r\ncombined and also produced materials which contributed well to several national programs in the SAT.\r\nRecurrent selection methods adopted with the help of genetic male sterile genes were not as effective\r\nas pedigree/backcross methods to achieve high yield. Discovery of genetic-cytoplasmic male sterility\r\nin 1954 enabled hybrid seed production cost effective, and it was established soon that hybrids were\r\nsuperior to varieties across all ranges of environments. Several high yielding hybrids were produced and\r\nreleased. Soon, lack of resistance to various yield constraints was recognized.\r\nCurrent research portfolios involve breeding of male-sterile and restorer lines in diversified\r\ncytoplasmic background for resistance to various yield constraints with high grain fodder yield. The\r\ngoal is to produce high yielding resistant cultivars. Future strategies of sorghum improvement for SAT is\r\nencoded in ICRISAT's Medium Term Plan which recognized a total of 29 production systems, five\r\nadaptation zones, and a multidisciplinary research strategy of producing high yielding resistant parents,\r\nand developing integrated pest, diseases, soil and water management methods."^^ .
