Abstract

One of the major questions that has confronted alfalfa workers since the reporting of pollen sterility is whether or not pollinating insects will consistently visit, or alternately visit, pollen producing plants and nonpollen producer to accomplish good crossing and the production of hybrid seed. Shortly after receiving a plant of 20 DRC our Company observed that one or two isolated plants growing in the midst of normal pollen producers was well pollinated and set a good crop of seed, with honey bees as pollinators. (Subsequent testing of this particular hybrid seed has proven it to be of no commercial value) By outcrossing 20 DRC with a few progeny tested clones we have since recovered a number of pollen sterile clones, one of which was used in the study I am reporting here.
