Abstract:
Nine interspeci ic crosses obtained from crossing L.usitatissimum with two strains of L. bienne and seven strains of L. grandi lorum -1 were studied in detail for various morphological characters like days to maturity, No. of branches plant , pollen fertility (%), lower size (mm), seed color, 1000 seed weight (g), crossing ef iciency (%), capsule set, cell size (μm), stomata size (μm), and growth habit. Interspeci ic hybrids were generally intermediate for certain morphological characters studied. However, some of them exhibited vigor for characters like days to maturity, plant height, cell size, etc. The results suggested that the F cross-compatibility of 1 interspeci ic crosses was speci ic to the parents involved in cross and showed a wide variation of success in hybridization percent. The seed formation in the F plant was considerably reduced. the hybrids showed varying degrees of pollen and seed sterility despite their 1 chromosome pairing and separating regularly.
