Longitud de coleóptilo de trigos harineros y relación de rht_1 en diferentes profundidades de siembra

EVA ARENAS HERNANDEZ (2013)

"Los genes Rht_1 y Rht_2 tienen una relación negativa con la longitud de coleóptilo y por tanto de vigor de emergencia en el cultivo de trigo. En el presente trabajo se evaluaron diferentes números de segregantes de cada una de las 9 cruzas de líneas élite de trigos harineros de CIMMYT que contienen Rht_1 gen del enanismo, por líneas que contienen diferentes tipos de Rht (Rht_4, Rht_5 y Rht_13) que no se asocian tanto a la longitud del coleóptilo; pero al igual reducen altura de planta. Igual número de segregantes dentro de cada familia en F2 se sembraron en 5 y 15 cm de profundidad, durante dos ciclos de con la intención de saber si la siembra más profunda nos permite obtener coleóptilos más largos y reducir la frecuencia de Rht_1 en comparación con la siembra a 5 cm. No se encontraron diferencias significativas para longitud de coleóptilos en las diferentes profundidades, pero se reportaron diferencias altamente significativas (P≤0.01) entre cruzas al igual que para presencia y ausencia de Rht_1, tales resultados sugieren que el largo de coleóptilo es un carácter de difícil selección en siembras profundas, pero si se puede hacer una buena elección de progenitores para modificar la longitud de coleóptilos, los Rht alternativos funcionaron en éste experimento, el uso de un buen progenitor es el principal responsable para modificar la longitud del coleóptilo y mantener baja la altura de planta."

"The genes Rht_1 and Rht_2 have a negative relationship with the coleoptile´s length, and in consequence, with the emergency force in wheat. In this study, different segregating numbers of each of the 9 elite line crosses of bread wheat from CIMMYT that contain Rht_1 gene for dwarfism, crossed with lines that contain different types of Rht (Rht_4, Rht_5 and Rht_13) that are not so associated with the coleoptile´s length, but also reduce the plant height, were evaluated. The same segregating numbers within families were planted at a depth of 5 and 15 cm during two seasons with the objective of knowing if a deeper planting can give us larger coleoptiles and a reduction of the Rht_1 frequency in comparison with the planting done at a depth of 5 cm. No significant differences were found for coleoptiles lengths among the different planting depths, however, high significant differences (P≤0.01) were found among crosses, as well as for the presence and absence of Rht_1; these results suggest that the coleoptile´s length is a trait difficult to select in deep plantings; although, parental selection can be done to modify the coleoptile´s length. The Rht alternatives worked in this experiment, and the use of a good parental can be the principal reason to change the coleoptile´s length and for maintaining a short plant height."
