En el presente trabajo se determinó la actividad de alfa amilasas y el Falling Number (FN) en harinas de diez líneas experimentales de tritíceas cultivadas en el Campo Experimental de la Facultad de Agronomía, Universidad Nacional de La Pampa, Argentina. Se realizó la conversión de FN al Número de Licuefacción (LN) para obtener la linealidad de la...

The estimation of genetic parameters such as heterosis (Mh), heterobeltiosis (Hh), general combining ability (GCA) and specific combining ability (SCA) allows inferences about the predominant action of the genes, indicates the appropriate selection strategy, and facilitates identification of the best parents. The present study was carried out using...

Grain yield per unit area and some yield components of eighteen experimental strains and three dual-purpose cultivars of triticale were evaluated from 2009 to 2015 in Santa Rosa (36°37' S, 64°17' W), Province of La Pampa, Argentina, on a petrocalcic Paleoustol soil under natural conditions. The trial was conducted using a randomized complete block...

... However, heterotic effect in the subsequent generations may be lost when dominant gene effects are effective in the inheritance of the studied feature. Many researchers have reported high SCA, Ht and Hb values for these characteristics (Ahmad et al., 2017;Ferrari et al., 2018;Rajput and Kandalkar, 2018). While Ht of spike harvest index was positive in all groups in F1, Ht-Hb values were lower and negative in F2 generation due to the decrease of heterozygosity. ...
... Within the varieties, the values presented a similar trend, although variety 7 of late habit was the one that presented the highest average value of 54 seeds per ear, which is why this is directly linked to the number of spikelets per spike, according to Velasco et al. (2020) who obtained higher results fluctuating between 73 and 59 (NSS). However, Paccapelo et al. (2017) reported values that ranged between 39 and 28 seeds per spike. According to the results reported by Beji (2016), for the number of seeds per spike, it reports values of 34 to 20 seeds per spike in triticale. ...
