Selection indices to identify drought-tolerant grain sorghum cultivars.

Twenty-five cultivars of grain sorghum [Sorghum bicolor (L.) Moench] were examined under both drought stress and normal conditions in 4 experiments. In each condition, genotypes were evaluated in a factorial experiment using a randomized complete block design with 3 replications. Eight drought toler...

Moench] were examined under both drought stress and normal conditions in 4 experiments. In each condition, genotypes were evaluated in a factorial experiment using a randomized complete block design with 3 replications. Eight drought tolerance indices including stability tolerance index, mean productivity (MP), geometric MP, harmonic mean, stress susceptibility index, tolerance index, yield index, and yield stability index were estimated for each genotype based on grain yield under drought (Ys) and irrigated conditions (Yp). The results indicated that there were positive and significant correlations among Yp and Ys with geometric MP, MP, harmonic mean, and stability tolerance index, indicating that these factors are better predictors of Yp and Ys than tolerance index, stress susceptibility index, yield stability index, and yield index. Based on adjusted means at Yp and Ys, indices geometric MP, MP, harmonic mean, and stability tolerance index, unweighted pair group method with arithmetic mean cluster and biplot analysis, the most tolerant cultivars were ?9929020?, ?9929034?, and ?N 95B?.CICERO BESERRA DE MENEZES, CNPMS; FLAVIO DESSAUNE TARDIN, CNPMS; MILTON JOSE CARDOSO, CPAMN; EDSON ALVES BASTOS, CPAMN; ARLEY FIGUEIREDO PORTUGAL, CNPMS; ROBERT EUGENE SCHAFFERT, CNPMS.2014-12-03T11:11:11Z2014-12-03T11:11:11Z2014-12-0320142017-09-27T11:11:11Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleGenetics and Molecular Research, Ribeirão Preto, v. 13, n. 4, p. 9817-9827, 2014.http://www.alice.cnptia.embrapa.br/alice/handle/doc/100144510.4238/2014.November.27.9enginfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da EMBRAPA (Repository Open Access to Scientific Information from EMBRAPA - Alice)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAMENEZES, C.
