TY - JOUR A1 - Pritchard, AJ T1 - Inheritance of two seedling characters in Sorghum almum Parodi, and cross pollination within S. almum and between S. almum and S. halepense (L) Pers. JF - Australian Journal of Agricultural Research JO - Aust. J. Agric. Res. Y1 - 1965 VL - 16 IS - 4 SP - 533 EP - 540 KW - UR - https://doi.org/10.1071/AR9650533 N2 - An albino seedling character in Sorghum almum Parodi was shown to be tetrasomically inherited. Segregation ratios for a pale green seedling character were very variable, and it is probable that more than one gene is involved. With the albino seedling character as a marker gene, it was found that the average natural crossing in S. almum was approximately 54% at one location and 70% at another. The maximum natural crossing between S. almum and S. halepense (L.) Pers. was 57%, but the mean was only 20%. This may indicate that some S. almum plants exhibit a degree of genetic isolation from S. halepense when these species are grown together under natural conditions. ER -
