摘要:

SUMMARYResults are reported of crossing a dwarf seed stalk line (mean height 44.8 cm) from Israel with five inbred lines of the Rijnsburger type each having normal tall seed stalks (mean heights 83.1–105.9 cm). The seed stalk height of F1generations from these crosses was slightly greater than that of the Rijnsburger parents but segregation occurred in the F2giving plants which could be considered ‘dwarf’ and ‘normal’ with respect to seed stalk height. Selfing individual F2‘dwarf’ plants produced F3progenies whose mean heights were in the dwarf range, and were significantly correlated with those of their F2parent. The results obtained in the F2and F3families suggest that although a major recessive gene for dwarfness may be present, substantial minor gene and environmental variation is
