The distribution pattern of Bullacta exarata was studied in different seasons of 2004 at south shore of Hangzhou Bay, China. We found that the distribution pattern of B. exarata was aggregated in each season by Taylor's power regression and Iwao's plot regresses methods (P < 0.001). Based on two-way ANOVA analysis, the results indicated that the densities were significantly affected by the fact...

introduction studies on the fall-winter sowing of chickpea were commenced in 1974-75 at mediterranean regions. for example, singh et al, (1997) studied some chickpea cold and ascochyta blight tolerant genotypes in fall-winter sowing for 10 years (1983-1993) on three regions in syria and lebanon under rain-fed conditions. the mean of seed yield for 10 years in the fall-winter sowing was 1686 kg....

With the aim of estimating genetic parameters and identifying superior popcorn combinations, 10 parents were crossed in a circulant diallel and evaluated together with the 15 resulting hybrids at two locations in two growing seasons for grain yield, number of broken plants, number of partially husked ears and popping expansion. The hybrids were less sensitive to environmental variations than th...
