Differential vegetative and reproductive performances among fifteen guinea grass hybrids

Abstract: _ The main scope of this work was to detect (Panicum maximum Jacq.) genotype differences as to morphoagronomic and seed quality indices, and to establish character correlations useful for determining vegetative and reproductive trends. Besides the flowering cycle, eight phenological and two seed quality traits were scored in a greenhouse randomized complete block experiment, as follows: plant height (PH), reproductive tiller number/overall tiller number (RTN/OTN), panicle number/reproductive tillers (PN/RT), l… Show more

“…2). The size differences may be due to hybridization between genotypes (Usberti-Filho et al 2002) or the multiplication of ploidy level, given that Guinea grass is known to have sexual diploids, and facultative to strict apomictic tetraploids and higher ploidy levels (7 9 and 11 9) (Kaushal et al 2015). These morphologic and genotypic differences play an important role in selecting morphotypes for agricultural use and may inform the management of morphologically distinct invasive forms.…”
