“…The strong direct contributions of harvest index to seed yield (Table 4) also suggest its importance for sesame yield improvement. Donald (1962) and Donald (1976) supported the use of harvest index as yield predictor in cereals. Both argued that if breeding for higher yield leads to a high harvest index, the corollary is true that breeding for higher harvest index is a useful approach to higher grain yield.…”

Sesame (Sesamum indicum L) is one of the major oil crops with potential for production by small-scale holders in the marginal agro-ecological zones of Kenya. Variability studies on yield and yield components of sesame mutant lines now in M7generation was carried out in two locations for two seasons in Kenya. The objective of the study was to assess performance of the mutant lines developed through induced mutational breeding. According to mean performance, the thirty selected mutant lines and four check cultivars showed a wide range of genotypic variability for all the studied traits. Seed yield per plant registered the highest coefficient of correlation (63.8%). In addition, seed yield had positive and significant (P<0.05) correlation with biomass yield, harvest index and 1000-seed weight. It showed a weak positive association with plant height, oil content, number of capsules per plant and number of days to flowering. Biomass yield, harvest index, 1000 seed weight and oil content had positive direct effect on seed yield. Line Mun 096/1/k5/2/4 was superior to the best check cultivar Spssik 116.

“…This could be due to high grain yield in variety Shorima and Kakaba as compared to others. Similarly, Donald and Hamblin (1976) reported that grain yield is proportional to HI and factors which make up grain yields such as grain weight and grains per spikelet have a relatively high effect on harvest index.…”

A B S T R A C TWith the objective of determining the effect of seed rates on the growth parameters, yield components, yield and protein content of bread wheat varieties, a study was conducted at Kulumsa Agricultural Research Center from July to November 2012. Four varieties (Digalu, Danda'a, Kakaba and Shorima) and five seed rates (100, 125, 150, 175 and 200 kg haG 1 ) and RCBD with three replications were used. The results showed that days to 50% heading, days to 90% physiological maturity, plant height, spike length, hectoliter weight and Harvest Index (HI) were affected highly significantly (p<0.01) by the main effects of variety and seed rate whereas, grain protein content was affected highly significantly (p<0.01) only by variety and above ground dry biomass yield was affected highly significantly (p<0.01) only by the main effect of the seed rate. Furthermore, the interaction effect of variety and seed rate significantly affected thousand kernels weight, number of effective tillers and number of kernels per spike and grain yield. The use of 150 kg haG 1 seed rate for variety Shorima resulted in highest thousand kernels weight (39.48 g), number of kernels per spike (60.23) and grain yield (5339.3 kg haG 1 ). From the result of this study, the use of 125 kg haG 1 seed rate for variety Danda'a; 150 kg haG 1 for varieties Shorima and Kakaba and 175 kg haG 1 for variety Digalu were identified for good crop stand and finally the yield.

“…Para tais culturas, a produtividade aumenta com o aumento da densidade, até um valor máximo, decrescendo em seguida (Duncan, 1984(Duncan, e 1985. O número ótimo de plantas é aquele que corresponde à máxima produtividade econômica, porém a produtividade biológica dessas culturas também apresenta relação assintótica quando relacionada com a população (Donald & Hamblin, 1976).…”
