Deskripsi

Leaf growth and development characteristics are important factor for grain yield. In order to genetic analysis of Leaf growth and development characteristics of rice, a linkage map provided from F2 rice mapping population  caused Gharib × Khazar and 111 microsatellite markers. Total number leaf, Days to flag leaf, leaf emergence rate, grain weight, grain number, length and width of flag leaf and branches number were mapped. qGW-1b, qFG-1b and qWFL-7 were identified as major effect on chromosome 1 and 7 and explained  14.30, 13.70 and 20.32% of total variation of grain weight, filled grain and width of flag leaf, respectively. The most of variation of total leaf number explained by 2 QTLs (over than 20%). According to these result, we can produced rice lines that have low vegetative growth periods and high total leaf number.
