“…This clustering pattern suggests that interspecific diversity does not necessarily represent genetic diversity; this might be due to free exchange of genetic material among different species and also due to natural and artificial selection forces resulting in perpetuation and stabilization of similar genotypes. These results were in agreement with the results reported earlier by Budhanwar et al, (2010), Belete et al, (2011), andSingh (2012), Doddabhimappa et al, (2010), Singh (2012, Neeru et al, (2015) and Avtar et al, (2017).…”

“…High genetic advance and moderate heritability were shown in the number of primary branches, total siliquae count, total seed yield/plot, and biological yield/plot in which both additive and nonadditive gene actions may be expressed. A parameter having low heritability coupled with high genetic advance revealed the additive gene effects of traits (Belete et al, 2011). The low heritability is due to high environmental effects, and selection per se may be ineffective for such traits as harvest index in the present study.…”

The response to selection in any crop improvement program depends on the degree of variance and heritability. The objective of the current study was to explain variance and heritability components in Indian mustard Brassica juncea (L). Czern & Coss to recognize promising genotypes for effective breeding. Two hundred and eighty-nine diverse accessions of Indian mustard belonging to four continents were analyzed for yield and yield-related traits (20 traits) over two seasons (2017–2018 and 2018–2019) using an alpha lattice design. The genetic variance was found to be significant (P ≤ 0.01) for the individual and under pooled analysis for all of the evaluated traits, demonstrating the presence of significant genetic variability in the diversity panel, which bids greater opportunities for utilizing these traits in future breeding programs. High heritability combined with high genetic advance as percent of mean and genotypic coefficient of variation was observed for flowering traits, plant height traits, seed size, and seed yield/plant; hence, a better genetic gain is expected upon the selection of these traits over subsequent generations. Both correlation and stepwise regression analysis indicated that the main shoot length, biological yield, total seed yield, plant height up to the first primary branch, seed size, total siliqua count, days to flowering initiation, plant height at maturity, siliquae on the main shoot, main shoot length, and siliqua length were the most significant contributory traits for seed yield/plant. Also, promising genotypes were identified among the diversity panel, which can be utilized as a donor to improve Indian mustard further. These results indicated a greater scope for improving seed yield per plant directly through a selection of genotypes having the parsimonious combination of these nine traits.

“…Esta informação relevante demonstra que estes genótipos podem ser utilizados em cruzamentos, pois segundo Belete et al (2011), o cruzamento entre genótipos com maior divergência genética possibilita a obtenção de populações altamente segregantes, com maior probabilidade de encontrar genótipos transgressivos para múltiplas características. Além da dissimilaridade, para a escolha de genitores é importante que se tenha elevado desempenho per se, o que já foi confirmado para todos os genótipos em trabalhos anteriores (Gonçalves Neto et al, 2011;Viana et al, 2011;Andrade Júnior et al, 2012;Azevedo et al, 2014 Silva et al (2011) evidencia uma base genética restrita entre os genótipos avaliados.…”

RESUMOAtentando-se à necessidade de adoção de sistemas agrícolas mais sustentáveis, é importante que os programas de melhoramento de batata-doce procurem aumentar além da produtividade de raízes a produtividade e a qualidade de ramas para a produção de silagem. Objetivou-se avaliar a divergência genética e a importância de caracteres associados à produção e qualidade de silagem de ramas em genótipos batata doce. O experimento foi conduzido no Campus JK da Universidade Federal dos Vales do Jequitinhonha e Mucuri no delineamento experimental em blocos casualizados, com 12 tratamentos e quatro repetições. Foram avaliadas doze características de ramas e silagem. Verificou-se variabilidade genética entre os genótipos, sendo possível a seleção de genitores divergentes para futuros programas de melhoramento para produção de silagem. Os genótipos BD-54 e BD-31TO foram os mais divergentes em relação aos demais, sendo indicada a sua utilização em cruzamentos visando o melhoramento da cultura para silagem, uma vez que o elevado desempenho per se de todos os genótipos avaliados já foi verificado em trabalhos anteriores. As características Na, NDT e FDN foram aquelas que mais contribuíram para a divergência.

The objective of this study was to evaluate the genetic diversity and the importance of traits related to production and quality the of silage of vines of sweet potato genotypes. The experiment was conducted on the JK Campus of the Federal University of Vales do Jequitinhonha e Mucuri, in a randomized-block design with 12 treatments and four replicates. Twelve traits of vines and silage were evaluated. Genetic variability was detected among the genotypes, allowing for the selection of divergent genotypes for future breeding programs for silage production. Genotypes BD-54 and BD-31TO were the most divergent, and so they are indicated for use in crosses aiming at the breeding of this crop for silage-making, given that the high performance per se of all evaluated genotypes has already been verified in previous studies. The Na, TDN, and NDF traits were those that most contributed to divergence.
