ABSTRACT This study aimed to estimate the genetic parameters, genetic correlations, genetic dissimilarity, and predicted gains with the selection of interspecific apomictic Paspalum plicatulum × Paspalum guenoarum hybrids in relation to seed yield traits. Nineteen genotypes that showed increased forage yield in previous studies were planted in a randomized complete block design with ten blocks. Traits evaluated in this study were: number of tillers/plant, number of reproductive tillers/plant, number of racemes/inflorescence, number of seeds/inflorescence, weight of a thousand seeds, and […]

The objective of this study was to evaluate the relation between the physical and morphological characteristics of semen from Bos taurus taurus and Bos taurus indicus cattle, the age of the bull and semen collection periods. Observations were made on 42 bulls with ages ranging from 12 to 174 months in five classes: subspecies Bos taurus taurus – 12 to 36 months; 37 to 60 months, 61 to 84 months, 85 to 108 months and 109 to 138 months and […]
