He said, 'Our scientists in collaboration with the Chinese partners have developed 13 CMS lines out of which one variety is giving 75 maund per acres and average grain length
of 7 mm, slightly short of the target of 80 maund per acre.'
Summary of joint analysis of variance for grain yield (GY), plant height (PH), panicle length (PL), number of filled grains per plant (NFGP), filled grain percentage (%FGP), number of stems per [m.sup.2] ([NSM.sup.2]), number of panicles per [m.sup.2] ([NPM.sup.2]), grain length
(GL), grain width (GW), grain length
/ width ratio (GLWR), 100-grain weight (100GW) evaluated in 25 rice genotypes cultivated in two environments in the State of Minas Gerais, Brazil.
Grain shape is determined by grain length
(GL), grain width (GW), length to width ratio (LWR) and grain thickness (GT).
Both the varieties have average grain length
(AGL) of 8.1-8.4mm and a per acre paddy yield of 2.0-2.4 tonnes compared with 7.0 to 7.4mm AGL and 1.2 to 1.7 tonnes yield of Super Basmati.
The relative error of the final diameter consists of the relative errors in the measurement of change in fuel grain mass, fuel density, and fuel grain length
and can be estimated by (10).

For comparison, grain length
of nine Basmati 370 accessions acquired from the National Small Grains Collection, but not grown at Stuttgart in 2001, ranged from 6.07 to 6.83 mm.

Agronomic traits for which data were collected were plant height, number of tillers/plant, number of effective tillers/plant, panicle weight, panicle length, number of spikelets/panicle, number of unfilled grains/panicle, number of grains/panicle, panicle fertility (%), days to 50% flowering, days to maturity, grain length
, grain width, grain length-width ratio, 1000 grain weight, grain yield/plant, straw yield/plant and harvest index (%).
ANOVA results did not show significant different for leaf width (F = 1.185, P>0.05), leaf area (F = 0.838, P>0.05), AFRGM scores (F=0.738, P>0.05), number of tillers per stand (F=1.032, P>0.05) and grain length
(F = 0.916, P>0.05).
decreased with enhancement of irrigation level, so that the least and highest measure of this dimension was reached in S0 and S2, respectively (Figure 3).
(2000) reported three QTL for grain length
, located on chromosomes 3, 6, and 7 and three QTL for grain width on chromosomes 1, 5, and 8, respectively.
