WIDE DISTRIBUTION OF EARLY-RIPENING VARIETIES WITH DETERMINATE GROWTH HABIT AS APPROACH FOR BUCKWHEAT YIELD STABILIZATION.
2015
Fesenko, A.N.
In the review, the basic features of buckwheat were discussed which limited yield growth of this crop. It was shown that breeding of varieties with determinate growth habit allowed significantly increase buckwheat yield in Russia. To stabilize grain production, it is necessary to create high-yielding and early ripening varieties with determinate growth habit. New perspectives in breeding for earliness opens mutations that cause a reduction of the number of flowers in the inflorescence: it supports pathway toward simultaneity of plants ripening, and increase supplying of every ripening seed. A possible breeding pathway to improve the homeostasis of buckwheat seed formation is interspecific hybridization with a wild species F. homotropicum which characterized by capacity for adaptive regulation of seed development together with low inbreeding depression.
