Resumo: | This work is related to 45 recently developed forage sorghum varieties. It aims to offer to Pernambuco Semi-Arid region farmers forage sorghum (Sorghum bicolor L.) varieties with higher yield capacity. The trials were carried out in Caruaru, São Bento do Una, Arcoverde and Serra Talhada involving nine different environments made up with combinations of years and localities. The experimental design was in randomized blocks with three replications in 1982, and without replications in 1983 and 1984. Analysis of dry matter (DM) productivity stability was also realized using the linear regression coefficient following the Eberhart & Russel Model. Progenies 467-4-2, 380-5-1, 322-1-3 and 484-1-1 showed outstandig behavior across the environments. The two first ones yielded 12.47 and 11.45 t/ha of DM and had a linear regression b = 1.03. The last two ones yielded 10.67 and 10.49 t/ha of DM and had a linear regression b = 0.90, which characterizes them as adapted to a less favorable environment. The sorghum variety IPA 7301218, previously recommended for planting in Pernambuco, had inferior performance among all other treatments. |

Este trabalho relata o desempenho de 45 novas progênies de sorgo forrageiro (Sorghum bicolor L.) objetivando propiciar aos produtores do Semi-Árido de Pernambuco cultivares de sorgo mais produtivas. Os testes foram conduzidos em Caruaru, São Bento do Una, Arcoverde e Serra Talhada, totalizando nove ambientes distintos, formados pelas combinações de anos e locais. O delineamento experimental foi o de blocos ao acaso, com três repetições, em 1982, e sem repetição, em 1983 e 1984. Efetuou-se, também, a análise de estabilidade da produtividade de matéria seca, pela estimativa do coeficiente de regressão linear, de acordo com o modelo proposto por Eberhart & Russel. As progênies 467-4-2, 389-5-1, 322-1-3 e 484-1-1 destacaram-se favoravelmente nas avaliações. As duas primeiras apresentaram uma produtividade média de 12,47 e 11,45 t/ha, respectivamente, de MS, e um coeficiente de regressão linear b = 1,03 que as caracterizam como estáveis. As duas últimas apresentaram uma produtividade média de 10,67 e 10,49 t/ha de MS, respectivamente, e um coeficiente de regressão linear b = 0.90, que as caracterizam como adaptadas a ambiente menos favorável. A cultivar de sorgo forrageiro IPA 7301218, previamente recomendada para plantio em Pernambuco, teve um desempenho inferior a todos os demais tratamentos.
