The fruit yield and morpholgical characters of F$_{1}$ hybrids between Capscium annuum L. 'California Wonder', four native Japanese cultivars, and three Korean F$_{1}$ cultuvars were evaluated and the results compared with parental cultivars. The F$_{1}$ hybrids obtained by crossing 'California Wonder' and native Japanese cultivars flowered 3 days earlier on average compared to parental cultivars. The yields of F$_{1}$ hydrids were higher than those of the parental cultivars, especially when one of the parents was 'California Wonder'. Also F$_{1}$ hybrid whose one parent was 'California Wonder' and 'Fushimi Amanaga' gave the highest fruit yield. The number of locules and seeds per fruit from of the 'California Wonder' hybrids whose one parent was 'California Wonder' was more than of the native Japanese cultivars. The plant height in F$_{1}$ hybrids obtained by crossing between 'California Wonder' and four native Japanese cultivars tended to be higher than that of the parental cultivars.

The capsaicinoid content of F$_{1}$ hybrids between annuum L. 'California Wonder', four native Japanese cultivars, and three Korean F$_{1}$ cultivars were evaluated and the results compared with parental cultivars. The capsaicinoid content was higher in the placenta than in fruit flesh. The placenta of 'Yatsufusa', 'Taka no Tsume', 'Cheongyang', 'Sinhong', and Geoseong' were the most pungent cultivatrs, with capsaicinoid content of more than 1000mg/100g DW, while 'California Wonder', and 'Fushimi Amanaga' contained trace amounts. Capsaicinoid content in F$_{1}$ hybrids varied with reciprocal crossing. Capsaicinoid content also varied with fruit development, rapidly increasing in the fourth or fifth week after flowering, and thereafter slowly declined.

In this study, we made a population with high biological efficiency (BE) to investigate the complex genetic architecture of yield-related traits in Agaricus bisporus. MB-013 crossed between bisp 015-p2 and bisp 034-p2, had high BE. Additionally MB-013 was an intervarietal hybrid that intercrosses with A. bisporus var. burnettii, bisp 015, and A. bisporus var. bisporus, bisp 034. One hundred and seventy homokaryons were selected using the cleaved amplified polymorphic sequence (CAPS) markers (PIN primer/HaeIII) from 300 single spore isolates (SSIs). One hundred $BC_1F_1$ hybrids were obtained by crossing the homokaryons of MB-013 with bisp15-p1. The population of 100 BC1F1 hybrids is suitable for analyses of BE.
