“…Lebsock and Amaya (1969) found average heritabilities of 0.67 for test weight and 0.72 for kernel weight in four durum crosses grown at two locations for 2 yr. Similar heritabilities have been reported for kernel weight in common wheat (T. aestivum L.): 0.73 by Sharma and Knott (1964), 0.61 by Johnson et al (1966), and 0.79 by Mou and Kronstad (1994). Test weight and kernel weight appear to be quantitatively inherited.…”

. Inheritance of test weight and kernel weight in eight durum wheat crosses. Can. J. Plant Sci. 89: 1047Á1057. High test weight and uniform kernel size are important grading factors for durum wheat [Triticum turgidum L. ssp. durum (Desf.) Husn.] because both are associated with semolina yield. The objective of this research was to determine the inheritance and heritability of test and kernel weights to facilitate development of selection strategies. Eight durum populations were grown in replicated, multi-location, multi-year field trials. Test weight and kernel weights were determined on all plots after harvest. Both traits were affected by genotype and to a lesser extent by year or location. Genotype environmental interactions were generally minor. Trial means for test weight ranged from 72.7 to 81.0 kg hL (1 and from 31.5 to 50.9 mg for kernel weight. All populations showed bidirectional transgressive segregation for both traits, and the estimated number of effective factors controlling them ranged from 4 to 23, indicating quantitative inheritance. With the exception of one population, heritability of test weight ranged from 0.80 to 0.92 and of kernel weight from 0.83 to 0.93. Both traits generally showed positive phenotypic and genotypic correlations with plant height. Also, mean test weight and kernel weight were higher for the gibberellic acid-sensitive (tall) than for the insensitive (semidwarf) group within populations segregating for gibberellic acid response. ], car tous deux sont lie´s au rendement en semoule. L'e´tude devait e´tablir l'he´re´dite´et l'he´ritabilite´de ces deux facteurs en vue de faciliter l'e´laboration de strate´gies de se´lection. À cette fin, les auteurs ont cultive´huit populations de ble´dur en pleine terre ap lusieurs sites et pendant plusieurs anne´es, avec re´plication. Ils ont mesure´le poids spe´cifique et le poids de l'amande dans toutes les parcelles apre`s la re´colte. Les deux caracte`res sont affecte´s par le ge´notype et dans une moindre mesure par le lieu ou l'anne´e. Les interactions entre le ge´notype et l'environnement sont ge´ne´ralement minimes. Le poids spe´cifique moyen e´tabli lors des essais variait de 72,7 a`81,0 kg par hL tandis que le poids moyen de l'amande fluctuait de 31,5 a`50,9 mg. Les populations pre´sentaient toutes une se´gre´gation transgressive bidirectionnelle pour ces caracte`res. On estime que 4 a2 3 facteurs efficaces les commandent, signe d'une he´re´dite´quantitative. Sauf pour une population, l'he´ritabilite´du poids spe´cifique varie de 0,80 a`0,92 tandis que celle du poids de l'amande fluctue de 0,83 a`0,93. Les deux caracte`res pre´sentent ge´ne´ralement des corre´lations phe´notypiques et ge´notypiques positives avec la taille du plant. D'autre part, chez les populations ou`il y a se´gre´gation de la re´action a`l'acide gibbe´rellique, le poids spe´cifique et le poids de l'amande moyens e´taient plus e´leve´s chez les varie´te´s sensibles a`l'acide gibbe´rellique (cultivars de haute taille) que chez celles qui ne le sont pas (semi-nain...

“…High restrict sense heritability values for plant height were found by several authors (Johnson et al, 1966;Camargo et al, 1980Camargo et al, , 2000a, thus, indicating that this trait is controlled by a few genes (Camargo & Oliveira, 1981b), with environment not playing an important role upon their expression. Consequently, successful selection in segregating populations can be performed in the F 2 generation.…”

Primary root growth is very important for wheat (Triticum aestivum L.) crop in upland conditions in the State of São Paulo. Fourteen wheat genotypes (mutant lines and cultivars) were evaluated for primary root growth during 7 and 15 days of development in complete and aerated nutrient solutions, in the laboratory. In the first experiment, solutions with three pH values (4.0, 5.0 and 6.0) at constant temperature (24 ± 1°C), and in the second experiment, solutions with the same pH (4.0) but with three temperatures (18°C ± 1°C, 24°C ± 1°C and 30°C ± 1°C) were used. High genetic variability was observed among the evaluated genotypes in relation to primary root growth in the first stages of development in nutrient solutions independent of pH, temperature and growth period. Genotypes 6 (BH-1146) and 13 (IAC-17), tolerant to Al 3+ showed genetic potential for root growth in the first stages of development (7 and 15 days), regardless of nutrient solution temperature and pH. Genotypes 14 (IAC-24 M), 15 (IAC-24), 17 (MON"S" / ALD "S") × IAC-24 M 2 , 18 (MON"S" / ALD "S") × IAC-24 M 3 and 24 (KAUZ"S" / IAC-24 M 3 ), tolerant to Al 3+ , showed reduced root growth under the same conditions.

“…Estudos sobre as correlações entre caracteres mensuráveis em uma população permitem inferências sobre sua interdependência, isto é, se tendem ou não a permanecer associados nas progênies durante os sucessivos ciclos de seleção (JOHNSON et al, 1966;FONSECA e PATTERSON, 1968). Esse conhecimento é primordial quando o objetivo é a seleção simultânea (mais de um caráter), ou quando o caráter de interesse expressa baixa herdabilidade ou é de difícil mensuração (SANTOS e VENCOVSKY, 1986).…”

Conhecer como os caracteres agronômicos se correlacionam nas populações segregantes é primordial ao melhorista de plantas, principalmente quando o objetivo for seleção indireta, por meio de um caráter de fácil mensuração ou de maior herdabilidade correlacionado ao caráter de interesse de menor herdabilidade. Dessa forma, a partir da variabilidade observada em caracteres agronômicos nas gerações F2 e F3 de quatro cruzamentos de trigo, avaliados no ano agrícola de 2004, no Centro Agropecuário da Palma, do Centro de Genômica e Fitomelhoramento - FAEM/UFPel, localizado no município de Capão do Leão (RS), este trabalho teve como objetivos estimar: a) coeficientes de correlação genotípica, fenotípica e de ambiente entre os caracteres; b) coeficientes de trilha sobre o rendimento de grãos. Em todas as populações avaliadas, por meio das correlações simples, a seleção de plantas mais produtivas pode ser realizada pela seleção indireta sobre número de afilhos férteis por planta. Mediante a análise de trilha foi possível identificar o efeito indireto do caráter número de afilhos férteis como causador da formação da correlação entre outros caracteres (comprimento da espiga x rendimento de grãos, número de espiguetas da espiga x rendimento de grãos e número de grãos da espiga x rendimento de grãos), enfatizando que o número de afilhos férteis é o principal caráter a ser considerado na obtenção de ganhos em produção por planta.
