Study on Related Characteristics in the Breeding of a Long Ear Strain of Medicago Sativa;

The genes which control the spike length of the new wheat germplasm 241 located on chromosome and chromosome arms are studied by using "Chinese spring"monosomic series and ditelosomic series as testing lines in order to probe into the heredity of its favor characters such as giant spikes, big grains and high bearing.

Quantitative trait loci (QTLs) for rice panicle length under two nitrogen levels were mapped on to the molecular marker linkage map by using a rice doubled haploid population derived from a cross between IR64 and Azucena.

A double haploid (DH) population and a recombinant inbred (RI) population derived from a cross between a japonica male parent Azucena and indica female parents, IR64 and IR1552 respectively, were used in both field and pot experiments for detecting QTLs and epistasis for rice panicle length in different genetic background and different environments.

The GCA increase of ear length,kernels per row,1000-kernel weight can be effective in raising kernel weight of single ear’s GC
