Abstract

A new blackgram variety namely Chai Nat 80, a cross between Prajeen and NBG 5 varieties was studied for sprouts and yield in 1989 at chai Nat field Crops Research Centre.  An average yield from 21 locations was obtained at 250 kg/rai which was 14% higher yield than a recommended variety  namely  Phitsanuloke 2.  The seed weight of chai Nat 80 ws also 11 % higher than Phitsanuloke 2 (57.5 vs 51.7 g/1,000 seeds).  A higher stability of yields was also found with this variety.  Sprout weight obtained from chai Nat 80 vareity was also 6% higher than Phitsanuloke 2.  The ratio of seed weight to sprout weight of this variety was 1 to 6, compared with 1 to 5 of Phitsanuloke 2.  The sprouts also had sweet taste and crispiness without raw smell as comparison to those of Phitsanuloke 2.  A study of farmers' adoption of Chai Nat 80 was conducted in Phetchabun and Nakhon Sawan provinces indicated that Chai Nat 80 was farvorable and acceptable by all farmers interviewed.
