Leaf photosynthetic rate (Pl) of Shanyou 63 (SLI), a Chinese F1 hybrid cultivar with exceedingly high yield, was evaluated in comparison with those of two Japanese leading pure-line cultivars (JC), Ni...
The thermo-sensitive genic male sterile (TGMS) T29s line was sterile when exposed to daily mean temperatures of 24.1°C or above during the critical stage (from 15 to 11 days before heading). It was co...
The spikelets produced, amouting to as much as 71, 000 per m2 in a dense-planting plot, had been attained by combining of 487 panicles per m2 and 148.8 spikelets per panicle. The panicle number per m2...
Rice seedlings of cultivar Yu-Za 29 were planted by the conventional cultivation method with a planting density of 78.5 hills per m2 (dense planting) in Binchuan, Yunnan Province and achieved a paddy...
A new F1 hybrid bitter melon (Momordica charantia L.) named ‘Kumaken BP1’ has been bred using a gynoecious inbred line for the seed parent. ‘Kumaken BP1’ belongs to an Ao-chunaga (green semi-long) typ...
