Capsicum species are frequently described in terms of genetic divergence, considering morphological, agronomic, and molecular databases. However, descriptions of genetic differences based on anatomical characters are rare. We examined the anatomy and the micromorphology of vegetative and reproductive organs of several Capsicum species. Four Capsicum accessions representing the species C. annuum...

Three sugarcane clones viz., NI-98, NIA-2004 and BL4 were tested for induced somatic mutation using irradiation doses of 0, 10, 20, 30, and 40Gy. The treatments 30Gy and 40Gy exhibited negative impact on the agronomic traits under study. The dose 20Gy showed stimulating and enhancing effect on plant height and cane yield (kg/plot). The analysis of variance (mean square) for all the characters u...

Acytogenetic study was performed on 66 tetraploid cotton cultivars (Gossypium hirsutum L.) and their hybrids. The cultivars studied differed significantly in their chiasma frequency and distribution as well as chromosome pairing indicating their genetic differences. Adjacent and alternate quadrivalents were formed in most of the cultivars. A-A or D-D heterozygote translocations occurred in most...

The production of green maize is considerable important for various regions Brazil. It vital that breeding programs public institutions seek to meet the needs this market sector, which has a relevant social role, mainly on small properties. aim study was estimate inbreeding depression and genetic components (m + d) characters associated with quality in three populations different basis: variety...
