Effects of waxy and hulless genes on water absorption rate of crude grains in Hordeum vulgare L.

Isogenic lines of two Korean barley cultivars Kangbori and Olbori(Hordeum vulgare L.) were made by introducing waxy and hulless genes originated from Masankwamaek, Korean land race and Yonezawamochi, Japanease land race with the aim of developing new cultivars of good quality for various end product uses. Four isogenic lines of waxy-hulled, waxy-hulless, nonwaxy-hulless and nonwaxy-hulled lines developed from Masankwamaek/Kangbori*7 and Yonezawamochi/Olbori*7 crosses were examined to clarify the effects of those genes on the absorption rate of crude grains. The effects of waxy genes introduced on the absorption rate were so highly remarkable that they increased absorption rate. Also the correlation among water absorption rates with soaking time were showed out to be highly significant from two hours to twenty-four hour one another. Although heritabilities of water absorption rates in the broad senses were considerably high in all soaking times, sixteen hours and twenty-four hours of soaking treatments were typically higher than the others. The other genes besides waxy were also showed out to give miner effects on the water absorption rates of crude grains.
