ข้าวสายพันธุ์ดีเด่น KLG02008-19-2-4-3

Abstract

KLG02008-19-2-4-3, an promising non-glutinous, non-photoperiod sensitive rice line had been derived from a cross of KLG96001-3-1-2 and SPR90. The improved rice had been developed through the conventional breeding and selection method. The single cross hybridization had been made in 2002 at Klongluang Rice Research Center. An promising line has an erect and moderately strong clum with about 120 centimeters for transplanting and about 112 centimeters for seed broadcasting, 118 days maturity for transplanting and 114 days for seed broadcasting. Its grain yielding potential is up to 1,052 kilograms per rai or more under suitably good fertilizer and cultural practice. The interstation yield trail in wet season 2010 obtained and average grain yield of KLG02008-19-2-4-3 and Suphanburi 3 were 827 and 718 kilograms pre rai พespectively, which was higher than Suphanburi 3 by 109 kilograms per rai (15.18 percent). The promising line was good adaptation and better yield stability than Suphanburi 1, Suphanburi 2 and Suphanburi 3. Its seed was long and slender shape, which was about 4 weeks for seed dormancy. The property of cooked rice ware fluffy and moderately hard similar to suphanburi 1. An growing of KLG02008-19-2-4-3 is recommended in irrigated paddy of central plain, which must beware form the important rice diseases and insect pest due to its moderately susceptible reaction.
