Abstract There has always been an interest in devising breeding programs for designer foods that would benefit both the producer and consumer. The challenge today is transformation of agriculture from “subsistence farming” to “market and income generation oriented” production system for which sorghum with its diverse end uses can assume significant role. Breeding for end-use identity-specific genotypes is needed for increased profitability to the farmers. In the present study, 60 sorghum genotypes were evaluated over two years to identify genotypes suitable for semolina recovery and popping properties, i.e. popping efficiency and pop volume expansion. Semolina recovery ranged from 20.7% to 48.3%, while popping efficiency ranged from 0 to 77.5%. Semolina recovery had positive and significant association with endosperm texture (r = 0.62), grain density (r = 0.49) and grain hardness (r = 0.55) indicating that genotypes with corneous endosperm yield high semolina. Also, semolina recovery had significant positive correlation with popping efficiency (r = 0.49) indicating that genotypes suitable for semolina can also be used for popping. Genetic divergence studies indicated that out of three clusters formed, cluster II having guinea race germplasm lines are suitable for semolina and popping. The information generated and the genotypes identified will help in enhancing the demand for sorghum as an industrial crop.

鉴定适合特定最终用途的高粱基因型：粗面粉回收和爆裂

摘要 一直以来，人们都对设计有利于生产者和消费者的特制食品的育种计划感兴趣。今天的挑战是将农业从“自给农业”转变为“以市场和创收为导向”的生产系统，其中具有多种最终用途的高粱可以发挥重要作用。需要培育最终用途的特定基因型，以提高农民的盈利能力。在本研究中，在两年内对 60 种高粱基因型进行了评估，以确定适合粗粒小麦粉回收和爆裂特性（即爆裂效率和爆裂体积膨胀）的基因型。粗面粉回收率范围为 20.7% 至 48.3%，而爆裂效率范围为 0 至 77.5%。粗面粉回收率与胚乳质地呈显着正相关（r = 0.62），谷物密度 (r = 0.49) 和谷物硬度 (r = 0.55) 表明具有角质胚乳的基因型产生高粗面粉。此外，粗面粉回收率与爆裂效率显着正相关 (r = 0.49)，表明适用于粗面粉的基因型也可用于爆裂。遗传差异研究表明，在形成的三个簇中，具有几内亚种质系的簇 II 适用于粗面粉和膨化。生成的信息和确定的基因型将有助于提高对高粱作为经济作物的需求。49) 表明适合粗面粉的基因型也可用于爆裂。遗传差异研究表明，在形成的三个簇中，具有几内亚种质系的簇 II 适用于粗面粉和膨化。生成的信息和确定的基因型将有助于提高对高粱作为经济作物的需求。49) 表明适合粗面粉的基因型也可用于爆裂。遗传差异研究表明，在形成的三个簇中，具有几内亚种质系的簇 II 适用于粗面粉和膨化。生成的信息和确定的基因型将有助于提高对高粱作为经济作物的需求。
