KSK 133-A HIGH YIELDING, STIFF STEMMED AND EXTRA LONG GRAIN COARSE RICE VARIETY - M. Akhter; M. Ahmad. M. Ramzan; T. H. Awan (Journal of Animal and Plant Sciences, 2007)
A high yielding, stiff stemmed and extra long grain coarse rice variety was developed by crossing KS282 and advance line 4321. It was tested in series of station and national yield trials during 1991-2003 for yield performance reaction to insect pests and diseases and grain quality. It was compared with KS282 in 64 trials. It exceeded KS282 by 7.58% and IR6 by 5.16% in station trials. In national trials i.e. NURYT 1998 and 1999, it out yielded KS282 by 7.77 %. In regional adoptability trials its superiority over local check was 10%. Overall, it had 8.6% and 18% yield edge over KS282 and IR6, respectively. The stem and leaves of KSK 133 remains green at the time of maturity. Therefore, can be used as a green fodder. It had similar response to insect pests and diseases as KS282. The new variety KSK133 is moderately resistant to bakanae / foot rot and paddy blast. In physico-chemical tests conducted at Rice Research Institute, Kala Shah Kaku, head rice recovery and grain length are more than KS282. Its grain is bold so it can not be mixed with any Basmati variety. It was approved for cultivation by Punjab Seed Council, Government of the Punjab and VEC at the Federal level in 2006.
